Impact response of glass fibre reinforced composites: A comparison between finite element results and experimental data

Abstract

Due to the difficulties in conducting experimental tests to obtain material properties at high strain rates, a technique has been developed for predicting the material data. These results have been used in a finite element analysis to simulate impact behaviour of glass fibre reinforced composites. High strain rate properties obtained by extrapolating results of experiments conducted at increasing but low to intermediate strain rates were used in a DYNA3D analysis of a simple three-point bend beam impact. Comparisons were made of the results predicted from this analysis and actual impact test data. Results show that the finite element model created may be used to predict the behaviour of woven and random glass laminates.
