Remaining Life Assessment of Damaged Reinforced Composites Under Inelastic Material Behaviour

Dalbir Singh

Abstract :

Role of composites in different applications ranging from aircrafts to sports equipments is always on the rise and this is due to many favourable properties of composites and also the research going on in material science. In this study, an investigation on remaining life of a typical bi–directional fie reinforced composite damaged during its design life, is done using a hyid method. Material testing, carried out on coupons as per ASTM standard with and without damage, is used as the basis for analytical studies done with non–linear finite element method. Different studies were carried out to assess the influence of different parameters of damage on the response in linear and nonlinear material behavior and based on these results, remaining life is assessed assuming that damage can occur at different levels of design load and curves are given to enable the loss due to damage to help in design and rehabilitation possibilities.
