【 摘 要 】

The durability of composite materials with metallic and non-metallic matrix can be calculated using both the uniaxial and biaxial loading of the composite, following the wear phenomenon that occurs in these cases. At the same time, this mode of loading of composite material offers multiple ways of analyzing crack resistance, because the wear phenomenon characteristic of these materials is composed of both the wear of the matrix and, in particular, the sliding wear and the crack-breaking behavior of the fibers. This paper proposes to approach the procedure of solving the specific equation systems with regard to the crack resistance, using for this purpose a composite panel with a rectangular surface, with a height w = 60 mm and a thickness t = 18 mm, subjected to loads variables. The model is considered to be loaded under a tension σct (MPa), both above and below the crack line.
