Abstract
Delamination tolerance is one of the key issues in laminated composites used in high technology structures. Delamination in these structures could grow due to repeated in-plane compressive loading during operation and the delamination tolerance levels are obtained by comparing mode-I SERR component with the corresponding fatigue threshold values. The Modified Virtual Crack Closure Integral (MVCCI) is used to estimate individual mode SERR components in a mixed-mode situation, which occurs at an embedded delamination. The present work proposed a numerical integration for the first time to evaluate the MVCCI for Hexa20 elements used in three-dimensional finite element analysis. Extensive numerical results are presented including a parametric study on a typical laminate.
