Finite Element Stress Analysis of Basalt/Epoxy and Carbon/Epoxy Composite Laminate with Varying Hole Configuration

Multiple holes in different patterns are present on composite structures for fastening purposes. The presence of holes in a structure results in a high stress gradient at the vicinity of their edges. This complex stress gradient results in a complicated failure mechanism near the hole. This study is...
