Download or read book Interlaminar Stresses Due to In-plane Gradient Stress Fields written by Kevin Jay Saeger and published by . This book was released on 2000 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interlaminar stresses that arise in composite laminates where gradients exist in in-plane stress fields are investigated. Two distinct mechanisms give rise to interlaminar stresses in generic problems, the presence of free edges and in-plane gradients. It is shown that the latter mechanism should be considered separately from the former and that interlaminar stresses from such in-plane gradients can be significant. A methodology to approximate these stresses through direct integration of the equilibrium equations is presented. The methodology involves the use of closed-form expressions of the in-plane stress field obtained by solving two-dimensional elasticity problems using homogenized material properties. As an example, the methodology is applied to the case of a laminate with a circular hole through which the importance of interlaminar stresses from in-plane gradients is demonstrated. The results show that the characteristics of the interlaminar stresses from in-plane gradients are very different from those of interlaminar stresses arising from free edges. Specifically, the parameters that affect the decay rates and magnitudes of the interlaminar stresses from the two mechanisms are found to be different. The current investigation provides new insights into interlaminar stress problems, in general, and offers a simple method for calculating the interlaminar stresses due to in-plane gradients.

This book was released on 2018-07-26 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The width and loading conditions effects on free-edge stress fields in composite laminates are investigated using a three-dimensional finite element analysis. This analysis includes a special free-edge region refinement or superelement with progrssive substructuring (mesh refinement) and finite thickness interply layers. The different loading conditions include in-plane and out-of-plane bending, combined axial tension and in-plane shear, twisting, uniform temperature and uniform moisture. Results obtained indicate that: axial tension causes the smallest magnitude of interlaminar free edge stress compared to other loading conditions; free-edge delamination data obtained from laboratory specimens cannot be scaled to structural components; and composite structural components are not likely to delaminate.

This book was released on 2012-12-06 with total page 858 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Conference on Fibrous Composites in Structural Design was a successor to the First-to-Third Conferences on Fibrous Composites in Flight Vehicle Design sponsored by the Air Force (First and Second Conferences, September 1973 and May 1974) and by NASA (Third Conference, November 1975) which were aimed at focusing national attention on flight vehicle applications of a new class of fiber reinforced materials, the advanced com posites, which afforded weight savings and other advantages which had not been previously available. The Fourth Conference, held at San Diego, California, 14-17 November 1978, was the fi rst of these conferences to be jointly sponsored by the Army, Navy and Ai r Force together with NASA, as well as being the first to give attention to non-aerospace applications of fiber reinforced composites. While the design technology for aerospace applications has reached a state of relative maturity, other areas of application such as mi litary bridging, flywheel energy storage systems, ship and surface vessel components and ground vehicle components are in an early stage of development, and it was an important objective to pinpoint where careful attention to structural design was needed in such applications to achfeve maximum structural performance payoff together with a high level of reliability and attractive economics.

Download or read book Residual Stresses in Composite Materials written by Mahmood M. Shokrieh and published by Woodhead Publishing. This book was released on 2021-06-22 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The residual stress is a common phenomenon in composite materials. They can either add to or significantly reduce material strength. Because of the increasing demand for high-strength, lightweight materials such as composites and their wide range of applications; it is critical that the residual stresses of composite materials are understood and measured correctly. The first edition of this book consists of thirteen chapters divided into two parts. The first part reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses. There are also additional chapters on using mathematical (analytical and numerical) methods for the calculation of residual stresses in composite materials. These include the simulated hole drilling method, the slitting/crack compliance method, measuring residual stresses in homogeneous and composite glass materials using photoelastic techniques, and modeling residual stresses in composite materials. The second part of the book discusses measuring residual stresses in different types of composites including polymer and metal matrix composites. The addition of nanoparticles to the matrix of polymeric composites as a new technique for the reduction of residual stresses is also discussed. In the Second Edition of this book, each of the original chapters of the first edition has been fully updated, taking into account the latest research and new developments. There are also five new chapters on the theoretical and experimental studies of residual stresses in the composite integrated circuits; residual stresses in additive manufacturing of polymers and polymer matrix composites; residual stresses in metal matrix composites fabricated by additive manufacturing; the eigenstrain based method for the incremental hole-drilling technique; and the estimation of residual stresses in polymer matrix composites using the digital image correlation technique. Residual Stresses in Composite Materials, Second Edition, provides a unique and comprehensive overview of this important topic and is an invaluable reference text for both academics and professionals working in the mechanical engineering, civil engineering, aerospace, automotive, marine, and sporting industries. Presents the latest developments on theoretical and experimental studies of residual stresses in composites Reviews destructive and non-destructive testing (NDT) techniques for measuring residual stresses Discusses residual stresses in the polymer matrix, metal matrix, and ceramic matrix composites Considers the addition of nanoparticles to the matrix as a new technique for reduction of residual stresses in polymeric composites Introduces the latest advancements of research on the residual stresses in additive-manufactured polymer and metal matrix composites

Download or read book Reduction of Free-Edge Stress Concentration written by P. R. Heyliger and published by . This book was released on 1985 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper describes a quasi-three dimensional formulation and associated finite element model for the stress analysis of a symmetric laminate with free-edge reinforcement. Numerical results are presented to show the effect of the reinforcement on the reduction of free-edge stresses. It is observed that the interlaminar normal stresses are reduced considerably more than the interlaminar shear stresses due to the free-edge reinforcement. A proposed method of reducing the intensity of these large stresses is to reinforce the stiffness at the free edge by wrapping a lamina or collection of laminae around the free edge, forming a cap. The cap is intended to reduce the large displacement gradients near the free edge, thereby decreasing the interlaminar stresses and reducing the probability of delamination. Experimental studies indicate that a reinforcing cap is a viable method of maintaining laminate strength 15. The purpose of this study is to determine the effect of a reinforcing cap on the stress distribution in a symmetric composite laminate under uniform axial extension. Parametric studies are performed by varying the thickness, length, and lamination scheme of the cap. Numerical results are presented for several representative test cases.
