Available in PDF, EPUB and Kindle. Book excerpt: The brick-mortar bond or interface is often the weakest link in the masonry composites. The localization of fracture processes at this bi-material interface plays an important role in the failure of this assemblage. These micro-level fracture processes control the nonlinear behavior of the brick-mortar interface which significantly affects the global behavior of the masonry structure at the continuum macro level. 2D Lattice-based micro-level fracture simulations which are based on Voronoi tessellation to discretize the continuum brick and mortar domains are applied to study progressive debonding of brick-mortar interfaces in unreinforced masonry composites. An energy method is subsequently employed to obtain the energy release rate of the lattice mesh as the crack propagates which is determined by considering the variation in the global stiffness matrix of the mesh with respect to crack length change. This energy release rate is inserted into the Irwin type fracture relationship for plane strain to calculate the modulus of complex stress intensity factor and its mode 1 and mode 2 values which are independent of the distance from the crack tip in the lattice. The lattice results for the energy release rate and stress intensity factors are then validated by comparing with three classic fracture mechanics problems analytical solutions of which are available in the literature. Afterwards, the 2-D plane strain lattice formulation is applied to simulate interfacial fracture properties of conventional test configurations in masonry. The computational lattice model is capable of evaluating the fracture toughness of brick-mortar interface along with other fracture properties from basic strength properties of lattice struts, which are removed by erosion upon failure. This information is employed to upscale the lattice fracture arguments onto the meso-level to quantify the fracture energy formulation of traction-separation cohesive zone models in the context of continuum finite element simulations of heterogeneous media such as masonry. The fracture energy from the lattice is also used in homogenizing a heterogeneous anisotropic masonry unit cell under direct tension using energy equivalence concept to obtain a scalar damage parameter which could be utilized to model the nonlinear behavior of a homogenized isotropic continuum finite element.
Book Synopsis Interface Fracture and Delaminations in Composite Materials by : Leslie Banks-Sills
Download or read book Interface Fracture and Delaminations in Composite Materials written by Leslie Banks-Sills and published by Springer. This book was released on 2017-07-05 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I of this SpringerBrief presents the problem of a crack between two dissimilar isotropic materials and describes the mathematical background. A fracture criterion is discussed and Methods for calculating fracture parameters such as stress intensity factors using the finite element method and three post-processors are considered. Actual test data and both deterministic and statistical failure curves are presented.In Part II of the book, similar descriptions are given for delaminations in composite laminates. The mathematical treatment of this type of damage including the first term of the asymptotic expansion of the stress and displacement fields is considered. Numerical post-processors for determining stress intensity factors for these cases are reviewed. Two examples of specific laminates are presented: one with a failure curve and the other with a failure surface. Finally, beam specimens used for testing such failures are discussed.

Book Synopsis Fracture Mechanics of Electrically Passive and Active Composites with Periodic Cracking along the Interface by : Sergey Kozinov
Download or read book Fracture Mechanics of Electrically Passive and Active Composites with Periodic Cracking along the Interface written by Sergey Kozinov and published by Springer Nature. This book was released on 2020-03-21 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and timely review of the fracture behavior of bimaterial composites consisting of periodically connected components, i.e. of bimaterial composites possessing periodical cracks along the interface. It first presents an overview of the literature, and then analyzes the isotropic, anisotropic and piezoelectric/dielectric properties of bimaterial components, gradually increasing the difficulty of the solutions discussed up to the coupled electromechanical problems. While in the case of isotropic and anisotropic materials it covers the problems generated by an arbitrary set of cracks, for the piezoelectric materials it focuses on studying the influence of the electric permittivity of the crack’s filler, using not only a simple, fully electrically permeable model, but also a physically realistic, semi-permeable model. Throughout the analyses, the effects of the contact of the crack faces are taken into account so as to exclude the physically unrealistic interpenetration of the composite components that are typical of the classical open model. Further, the book derives and examines the mechanical and electromechanical fields, stress and electric intensity factors in detail. Providing extensive information on the fracture processes taking place in composite materials, the book helps readers become familiar with mathematical methods of complex function theory for obtaining exact analytical solutions.

Book Synopsis Application of Fracture Mechanics to Cementitious Composites by : S.P. Shah

This book was released on 2012-12-06 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland cement concrete is a relatively brittle material. As a result, mechanical behavior of concrete, conventionally reinforced concrete, prestressed concrete, and fiber reinforced concrete is critically influenced by crack propagation. It is, thus, not surprising that attempts are being made to apply the concepts of fracture mechanics to quantify the resistance to cracking in cementious composites. The field of fracture mechanics originated in the 1920's with A. A. Griffith's work on fracture of brittle materials such as glass. Its most significant applications, however, have been for controlling brittle fracture and fatigue failure of metallic structures such as pressure vessels, airplanes, ships and pipe lines. Considerable development has occurred in the last twenty years in modifying Griffith's ideas or in proposing new concepts to account for the ductility typical of metals. As a result of these efforts, standard testing techniques have been available to obtain fracture parameters for metals, and design based on these parameters are included in relevant specifications. Many attempts have been made, in the last two decades or so, to apply the fracture mechanics concepts to cement, mortar, con crete and reinforced concrete. So far, these attempts have not led to a unique set of material parameters which can quantify the resistance of these cementitious composites to fracture. No standard testing methods and a generally accepted theoretical analysis are established for concrete as they are for metals.

This book was released on 2021-03-26 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to raise awareness about the use of sustainable Textile-Reinforced Mortar (TRM) composite systems, including plant fibers, for civil engineering applications. It presents a comprehensive characterization of the mechanical properties of Flax-TRM composite systems when used for strengthening masonry elements. Moreover, it reports on a physical and mechanical characterization of the single components, such as the textile and mortar one. In turn, it describes tensile tests on the composite and shear bond tests on Flax-TRM-to-masonry substrate elements, carried out for the purpose of analyzing the composite material and its adherence behavior with a brick masonry element. It also reports on the analysis of the contribution of the reinforcement system on the shear capacity of masonry elements, carried out via diagonal compression tests. Last but not least, the book reports on some innovative solutions for improving the mechanical performance of the reinforcement system, e.g., by treating the fiber or modifying the matrix mix design, discussing the experimental findings in detail. All in all, this book offers extensive information on the use of plant fibers as reinforcement in TRM systems, specifically highlighting the potential of this composite as strengthening strategy for various civil engineering applications. Moreover, it defines key mechanical aspects of the composite that must be taken into consideration for increasing the efficiency of the reinforcing system. Last but not least, the book describes some technical solutions aimed at an overall improvement of the structural performance of sustainable textile-reinforced composite.
