Book Description
Composites are used extensively in engineering applications. A constant concern is the effect of foreign object impacts on composite structures because significant damage can occur and yet be undetectable by visual inspection. Such impacts can range from the most ordinary at low velocity--a tool dropped on a product--to the hypervelocity impact of space debris on a spacecraft. This book explains how damage develops during impact, the effect of impact-induced damage on the mechanical behavior of structures, and methods of damage prediction and detection. Numerous examples are included to illustrate these topics. Written for graduate students, as well as researchers and practicing engineers working with composite materials, this book presents state-of-the-art knowledge on impact dynamics while requiring only basic understanding of the mechanics of composite materials.

Book Description
The papers contained herein were presented at the Sixth International Conference on Composite Structures (ICCS/6) held at Paisley College, Scotland in September 1991. The Conference was organised and sponsored by Paisley College. It was co-sponsored by Scottish Enterprise, the National Engineering Laboratory, the US Army Research, Development and Standardisation Group-UK, Strathclyde Regional Council and Renfrew District Council. It forms a natural and ongoing progression from the highly successful ICCS/1/2/3/4 and 5 held at Paisley in 1981, 1983, 1985, 1987 and 1989 respectively. As we enter the final decade of this century many organisations throughout the world are adopting a prophetic role by attempting to forecast future scientific advances and their associated impact on mankind. Although some would argue that to do so is folly, without such futuristic visionaries the world would be that much poorer. IntelJigent speculation based on research trends and historical advances, rather than fanciful theories, breathes a healthy air of enthusiasm into the scientific community. Surely this is the very oxygen necessary to ignite the fir~s of innovation and invention amongst pioneers of research.

Book Description
A key design issue in the design of composite structures continues to be impact. Due to the limited capability of laminated composites to withstand transverse loadings and the subsequent reduction in their overall load-carrying capacity, impact can, in fact, be a/the limiting design issue in many applications. In order to effectively utilize composites, it is necessary to understand the impact issue and to develop techniques to assess the damage and resultant capability of composite laminates subjected to impact. The overall issue of impact and related issues have, therefore, received considerable attention in the structural design process, in the materials development world, and in the research community [Abrate, 1991]. Engineers and researchers have recently realized that it is necessary to divide the behavior of composite laminates and structures with regard to impact into the two separate aspects of damage resistance and damage tolerance [Cairns and Lagace, 1992]. Damage resistance is a measure of the damage incurred by a material or structure due to a particular event such as impact, while damage tolerance involves a measure of the ability of a material or structure to "perform", given particular requirements, with damage present. These two aspects are related only in that the damage tolerance of a structure depends upon the type, location, and extent of the damage present. The damage tolerance is not affected by how the damage got there (the damage resistance aspect) [Cairns and Lagace, 1990]. Although understanding and predicting the residual performance capability of the structure is the ultimate goal in considering impact, it has become clear [Lee and Zahuta, 1991, Guy and Lagace, 1992] that it is first necessary to characterize, on a three-dimensional basis, the damage which results due to an impact event. Only then can the proper models be formulated to characterize the performance of the composite structure based on the damage which actually exists. This can be facilitated by understanding the mechanics of the impact event and how the damage occurs such that methods can be developed to predict the damage state based on the characteristics of the impact event. In order to simplify the assessment of the behavior of composites subjected to impact, approaches have been formulated which treat the behavior as the sequential effect of a number of events. The flow of such an approach is shown in Figure 1 [Cairns and Lagace, 1992]. In this figure, italicized descriptions refer to output from a model to be used as input to the next step.

Book Description
Damage Modeling of Composite Structures: Strength, Fracture, and Finite Element Analysis provides readers with a fundamental overview of the mechanics of composite materials, along with an outline of an array of modeling and numerical techniques used to analyze damage, failure mechanisms and safety tolerance. Strength prediction and finite element analysis of laminated composite structures are both covered, as are modeling techniques for delaminated composites under compression and shear. Viscoelastic cohesive/friction coupled model and finite element analysis for delamination analysis of composites under shear and for laminates under low-velocity impact are all covered at length. A concluding chapter discusses multiscale damage models and finite element analysis of composite structures. Integrates intralaminar damage and interlaminar delamination under different load patterns, covering intralaminar damage constitutive models, failure criteria, damage evolution laws, and virtual crack closure techniques Discusses numerical techniques for progressive failure analysis and modeling, as well as numerical convergence and mesh sensitivity, thus allowing for more accurate modeling Features models and methods that can be seamlessly extended to analyze failure mechanisms and safety tolerance of composites under more complex loads, and in more extreme environments Demonstrates applications of damage models and numerical methods
