Abstract

The article presents an analysis of the strength and crack resistance of structures, in particular an L-shaped panel, using the finite element method. A methodology for estimating the limiting stress states of finite elements that determine the direction of crack growth based on criteria of linear elastic fracture mechanics is considered. Numerical simulation of an L-shaped panel under the influence of vertical load is carried out. The modeling included the discretization of the structure using the finite element method, the formation of stiffness matrices, and the study of limit states. The simulation results are in good agreement with experimental data for concrete structures.
