Computer Simulation of the Stress-Strain State of the Plate with Circular Hole and Functionally Graded Inclusion

Computer simulation of the behavior of a thin elastic rectangular plate with a circular hole and an annular inclusion made of functionally graded material has been carried out. Using the finite element method, the influence of the geometric and mechanical parameters of the inclusion on the concentration of stresses around the hole is investigated and various laws of the change in the modulus of elasticity of a functionally graded material are specified. A comparative analysis of the results has been carried out. The recommendations for reducing stress concentration are given.Computer simulation of the behavior of a thin elastic rectangular plate with a circular hole and an annular inclusion made of functionally graded material has been carried out.
