Abstract

A Review Paper on Study of Progressive Damage of Composite Structure under Tri Axial Loading by Using Micromechanical based Failure Theories

Highlights

Composite material is combination of two phases designed for better engineering properties
Paper reviewed laminate failure occurred by various means under tri axial loadings by using various micromechanics based failure theories applied under static loading conditions
Experimental data shows that the mechanical behaviour and progressive damage of composite laminates may be different under multi axial loading than under uniaxial loading conditions

Summary

INTRODUCTION

Composite material is combination of two phases designed for better engineering properties. Fibers are oriented in different directions to enable to achieve desired property configuration and strength. The property configuration of lamina and laminate is different from each other, and despite made of same material the ultimate load sustaining capacity and loading behavior is not same. The broad application of fiber-reinforced composite laminates has led to a large amount of research into their progressive damage and failure, and many authors have devoted their work in similar context. There are numerous progressive and failure models that predict mechanical response of structure which includes all loading configurations, boundary conditions, lay-ups, and thicknesses of composite laminates. Existing failure criteria are classified as micromechanics or macro mechanics based, the structure failure analysed at lamina constituent level is recognized micromechanical approach where failure analysis at. Authors and failure investigation work based on discussed throughout paper which project light on Micromechanical failure theories: nature of loading, factors responsible in failure, and Micromechanics Model
