Multi-Scale Analysis for Assessing the Impact of Material Composition and Weave on the Ultimate Strength of GFRP Stiffened Panels

A micro-meso-macro analysis framework based on the multi-scale method was employed to analyse mechanical behaviour of marine GFRP stiffened panels. The study aims establish a procedure for assessing impact material composition and weave ultimate strength assessment an essential step in design process, investigation construction materials has great benefit lightweight composite structures. micro- meso-scale RVE models components used are established, their failure criteria stiffness degradation created using user-defined subroutine VUMAT ABAQUS. equivalent properties at micro-scale (meso-scale) obtained by homogenisation define (macro-scale) finite element analyses. assesses macro-mechanics composites, it is shown that panels mainly determined CSM fibre bundles WR yarns. Parametric meso-mechanics can provide tool obtain optimal macro panel.
