Modelling low velocity impact induced damage in composite laminates
The paper presents recent progress on modelling low velocity impact induced damage in fibre reinforced composite laminates. It is important to understand the mechanisms of barely visible impact damage (BVID) and how it affects structural performance. To reduce labour intensive testing, the development of finite element (FE) techniques for simulating impact damage becomes essential and recent ef...
متن کاملLow Velocity Impact Damage Prediction in Laminated Composite Plates
In this paper, a finite element model is presented for the transient analysis of low velocity impact, and the impact induced damage in the composite plate subjected to low velocity impact is studied. The failure criteria suggested by Choi and Chang and the Tsai-Hill failure criteria are used for the prediction of the damage in the composite plate; then the effect of various parameters on the im...
متن کاملContinuum damage mechanics based modeling progressive failure of woven-fabric composite laminate under low velocity impact
A continuum damage mechanics (CDM) meso-model was derived for both intraply and interply progressive failure behaviors of a 2D woven-fabric composite laminate under a transversely low velocity impact. An in-plane anisotropic damage constitutive model of a 2D woven composite ply was derived based on CDM within a thermodynamic framework, an elastic constitutive model with damage for the fibre dir...
متن کاملDamage Assessment in Glass Fiber-Epoxy Matrix Composite under High Velocity Impact of Ice
This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...
متن کاملModeling of the Fatigue Life of Fiber Metal Laminates under Low Velocity Impact by Finite Element Method
In this study, first by using the finite element method, fatigue life of fiber metal laminates of Glare type subjected to impact was obtained and the numerical results of the model were compared with the experimental results. With regard to the very good matching between numerical and experimental results, then the results of the finite element model were generalized and expanded, and with usin...
