摘要：
A numerical and experimental analysis comparing the influence of specimen geometry, material composition and loading conditions on the crushing response of truncated conical shells is presented. The analysis is based on a new multi-layered numerical modelling composed of shell and solid elements. A material model appropriate for balanced fabrics has been developed including in-plane failure, delamination failure and resulting degradation models. (c) 2005 Published by Elsevier SAS.
