TLDR
The computing power that is available for engineering calculation continues to grow at a dramatic pace as mentioned in this paper and engineers in industry want to have seamless models that can be used to design across different domains.Abstract:

Damage and Failure of Composite Materials
TL;DR: In this paper, the authors provide a complete guide to composite material damage, fatigue, and failure, focusing on the underlying principles governing composite damage, reviewing basic equations and mechanics theory, before describing mechanisms of damage such as cracking, breakage and buckling.
Journal ArticleDOI
Residual stresses in thermoplastic composites - a study of the literature. Part III: Effects of thermal residual stresses
TL;DR: In this article, the effects of thermal residual stresses on the material properties of thermoplastic composites were discussed. And several mechanisms to relieve these residual stresses are proposed, as well as several mechanisms that can be used to relieve the residual stresses.
Journal ArticleDOI
An augmented finite element method for modeling arbitrary discontinuities in composite materials
TL;DR: An augmented finite element method (A-FEM) is presented in this paper, which is a variant of the method of Hansbo and Hansbo (Comput Methods Appl Mech Eng, 193: 3523-3540, 2004), which can fully account for arbitrary discontinuities that traverse the interior of elements.
Review of accelerated ageing methods and lifetime prediction techniques for polymeric materials.
TL;DR: In this article, the main degradation mechanisms present in polymeric materials, a review of techniques for predicting the life expectancy of polymers; standards for life-prediction; and the results of an industrial survey examining current UK practice.
Journal ArticleDOI
Progressive damage and failure modeling in notched laminated fiber reinforced composites
TL;DR: In this article, a model using thermodynamically based Schapery Theory (ST) to model progressive microdamage in the matrix phase is presented, which is not governed with a matrix failure criterion, but rather matrix failure occurs naturally through the evolution of microdamage.

Analysis of Composite Materials—A Survey
TL;DR: In this paper, the authors review the analysis of composite materials from the applied mechanics and engineering science point of view, including elasticity, thermal expansion, moisture swelling, viscoelasticity, conductivity, static strength, and fatigue failure.

Solutions for effective shear properties in three phase sphere and cylinder models
Richard M. Christensen,K.H. Lo +1 more
TL;DR: In this paper, the effective shear modulus of two types of composite material models are compared. And the results are found to differ from those of the well-known Kerner and Hermans formulae for the same models.

Damage modelling of the elementary ply for laminated composites
Pierre Ladevèze,E Ledantec +1 more
TL;DR: In this article, a model of fibrous composite laminate damage is modelled at the elementary-ply scale, where damage mechanics are used to describe the matrix microcracking and fiber/matrix debonding.
Journal ArticleDOI
Lamina properties, lay-up configurations and loading conditions for a range of fibre-reinforced composite laminates
TL;DR: In this article, the authors present a description of the laminates provided to all participants in an exercise to predict the strength of composite Laminates, including the elastic constants and the stress/strain curves for four unidirectional laminae.
