The nonstationary coupled problem of thermoelasticity in different spatial approximations

The work is dedicated to the development and investigation of the numerical algorithms for the numerical solution of the nonstationary coupled problem of thermoelasticity in spherically symmetric, plane one-dimensional and two-dimensional cases. The finite element and finite difference algorithms were constructed for these purposes. Their qualitative (for example total conservativeness influence) and quantitative properties 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 that depending on the time delay between impulses the result of the second impulse influence can be considerably changed and in particular its destructive action can be reduced.
