This book was released on 2021 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to develop strength and life prediction analysis tools for aircraft composite structures have shown a great need to understand the complexity and interaction of failure modes. Many failure models are highly sensitive to transverse nonlinear shear stress-strain and delamination fracture properties, which are notoriously hard to measure. Without proper input parameters, life predictions analyses will not be successful. The objective of this work was to accurately characterize these mechanical properties of carbon fiber reinforced polymer composites through advanced experimental methods. Full-field noncontact deformation measurements using Digital Image Correlation are used to quantify all surface strains components, enabling the design of experiments subject to complex loading. The presented splined-based optimization techniques link measured strains to applied loading, converging to accurate material properties without ad hoc assumptions on the material model. These methods improve on first-order closed-form and iterative numerical solutions due to flexibility and accuracy without the computational expense. Applications of the optimization model on the Short Beam Shear and Thick Adherend shear tests proved the usefulness of these methods. Full three-dimensional characterization of selected carbon fiber-reinforced polymer composites is presented with a discussion of the applicability of simplifying assumptions on the material model. This experimental program showed that the assumption of transverse anisotropy must be verified, as it may be inaccurate depending on the material. Furthermore, large shear strain response of IM7/8552 UD specimens has been measured by asymmetric three-point bending test. Applicability of the common D3518 ±45 degree off-axis tensile test was also deliberated. Shear stress-strain response measured from D3518 specimens disagrees with the Short Beam Shear and Small Plate Twist test results after about 5000 microstrain. This conclusion was shown to be influenced by the specimens' stacking sequence and microdamage which develops well before damage can be spotted in X-ray Computed Tomography reconstructions. High-magnification deformation measurements are applied to directly measure cohesive laws in precracked Double Cantilever Beam and Thick Adherend shear specimens. Supported by non-destructive in situ crack front measurements by Computed Tomography, the loaded crack tip displacements are directly related to the J-integral. The derived traction-separation law is verified by the excellent agreement of the global response between cohesive model Finite Element Analysis and measurements. This study was the first application of the direct measurement of mode II traction-separation law in Thick Adherend shear specimens.

Book excerpt: A combined theoretical and experimental study has been conducted on the delamination of fibre reinforced polymeric composites. The main objectives were to gain a better understanding of the physical origin of delamination fracture toughness and to develop theoretical models to predict the critical strain energy release rates of delamination in composite materials. Of the many energy dissipation mechanisms present in the delamination process, crack tip plastic deformation was determined to be the most critical one. Two analytical beam models, based on the double cantilever beam (DCB) specimen and the end notched flexure (ENF) specimen, were developed. A fracture criterion, based on the size of the crack tip plastic zone, was incorporated into these beam models so that the mode I and mode II critical strain energy release rates of composites can be predicted using the corresponding resin and fibre properties as well as composite structural parameters. A complete set of mechanical tests were performed on five polymeric composite systems, including both thermoset and thermoplastic systems, and on their corresponding neat polymer resins. The theoretical predictions for delamination fracture toughness from the present analytical models agreed very well with the data obtained in the present experiments and those in the literature over a wide range of composite laminates.

This book was released on 2011-07-14 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue has long been recognized as a mechanism that can provoke catastrophic material failure in structural applications and researchers are now turning to the development of prediction tools in order to reduce the cost of determining design criteria for any new material. Fatigue of Fiber-reinforced Composites explains these highly scientific subjects in a simple yet thorough way. Fatigue behavior of fiber-reinforced composite materials and structural components is described through the presentation of numerous experimental results. Many examples help the reader to visualize the failure modes of laminated composite materials and structural adhesively bonded joints. Theoretical models, based on these experimental data, are demonstrated and their capacity for fatigue life modeling and prediction is thoroughly assessed. Fatigue of Fiber-reinforced Composites gives the reader the opportunity to learn about methods for modeling the fatigue behavior of fiber-reinforced composites, about statistical analysis of experimental data, and about theories for life prediction under loading patterns that produce multiaxial fatigue stress states. The authors combine these theories to establish a complete design process that is able to predict fatigue life of fiber-reinforced composites under multiaxial, variable amplitude stress states. A classic design methodology is presented for demonstration and theoretical predictions are compared to experimental data from typical material systems used in the wind turbine rotor blade industry. Fatigue of Fiber-reinforced Composites also presents novel computational methods for modeling fatigue behavior of composite materials, such as artificial neural networks and genetic programming, as a promising alternative to the conventional methods. It is an ideal source of information for researchers and graduate students in mechanical engineering, civil engineering and materials science.

Available in PDF, EPUB and Kindle. Book excerpt: The use of decohesion elements for the simulation of delamination in composite materials is reviewed. The test methods available to measure the interfacial fracture toughness used in the formulation of decohesion elements are described initially. After a brief presentation of the virtual crack technique most widely used to simulate delamination growth, the formulation of interfacial decohesion elements is described. Problems related with decohesion element constitutive equations, mixed-mode crack growth, element numerical integration and solution procedures are discussed. Based on these investigations, it is concluded that the use of interfacial decohesion elements is a promising technique that avoids the need for a pre-existing crack and pre-interfacial decohesion elements is a promising technique that avoids the need for a pre-existing crack and predefined crack paths, and that these elements can be used to simulate both delamination onset and growth.

Book excerpt: This research concerns the analysis and prediction of delamination damage that occurs in composite structures on the sublaminate scale - that is, the scale of individual plies or groups of plies. The objective was to develop analytical models for fixed-mode delamination in composites. These include: (1) the influence of residual thermal and moisture strains; (2) local or transverse crack tip delamination originating at the tip of transverse matrix cracks; and (3) delamination in tapered composite under tensile loading. Computer codes based on the analytical models were developed and comparisons of predictions with available experimental and analytical results in the literature were performed.
