The Numerical Solution of the Problem on Impulse Thermal Pressure on the Layered Elastic Medium in Spherically Symmetric and Two-Dimensional Cases

The work is dedicated to the development and investigation of the calculated algorithms for the numerical solution of the nonstationary coupled problem of thermoelasticity in two-dimensional and spherically symmetric cases. The finite element and finite difference algorithms were constructed for these purposes. Their qualitative (for example total conservativeness impact) and quantitative proper- ties were investigated in theory and in tests. The developed algorithms were used for the solution of the problem of elastic layered body response on the supply of two thermal impulses. It is shown what depending on the time delay between impulses the result of the second impulse impact can be considerably changed and in particular its destructive action can be reduced.
