Extensive studies have been previously carried out on the effects of various types of local damage on the performance of sandwich panels used in the hull structures of naval ships. More recently, the approach was adapted for application on board a sp

A user defined cohesive material model is implemented in the LS-DYNA finite element code. The model is based on interface properties characterised from DCB specimens loaded with unequal bending moments. Different mode mixities are obtained by applyin

Nonlinear response in glass fibre non-crimp fabric reinforced vinylester composites

Autor: Reidar Kvale Joki, Brian Hayman, Frode Grytten

Publikováno v: Composites Part B: Engineering. 77:105-111

This paper addresses the nonlinear stress-strain response in glass fibre non-crimp fabric reinforced vinylester composite laminates subjected to in-plane tensile loading. The nonlinearity is shown to be a combination of brittle and plastic failure. I

Simplified ultimate strength analysis of compressed composite plates with linear material degradation

Autor: Brian Hayman, Qiao Jie Yang

Publikováno v: Composites Part B: Engineering. 69:13-21

Simply supported, rectangular, composite plates subjected to in-plane compressive load have been investigated for ultimate strength. An efficient, semi-analytical method has been established based on large deflection theory and first order shear defo

The cohesive law for Mode I delamination in glass fibre Non-Crimped Fabric reinforced vinylester is determined for use in finite element models. The cohesive law is derived from a delamination test based on DCB specimens loaded with pure bending mome
