Abstract
Strength of Space vehicles is a crucial issue for Space flight safety. The presence of latent defects in the material has a significant effect on the strength at different loads: the speed and direction of crack growth. In this paper, we study a three-dimensional elastic medium weakened by a system of plane cracks and one crack with a bend. As a numerical method, the method of boundary elements was chosen, namely, the method of discontinuous displacements. The code is implemented in C ++. A comparison was made with known analytical results. Bend crack behavior is studied for various loads.
