- Abstract
The durability of materials is a critical issue in space flight safety. The presence of latent defects in the material has a significant effect on the strength under 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. The numerical method of boundary elements (the method of discontinuous displacements) is used as a method. The code is implemented in C ++. Comparison with known analytical results. The behavior of bending cracks is studied for various loads. The present study was supported by the program of Russian Academy of Sciences “Development of algorithms and codes for multiscale processes and combustion simulations”.
