In this paper discrete damage mechanics (DDM) is used to predict inter-laminar transverse and shear damage initiation and evolution in terms of the fracture toughness of the laminate. The finite element method (FEM) is one of the most widely and most popular numerical methods for analyzing composite structures. therefore ANSYS commercial software is used for analysis of layered plate ... https://halohealthcarers.shop/product-category/aluminum-crutches/
