Abstract: | Finite-element discretization of equations of thermoviscoelasticity in solving problems of dissipative heating of elastomers carried out. The FEM equations produced on the basis of the moment system of finite elements can be used to calculate elastomer structures with an arbitrary degree of compressibility. Examples of solving test problems are used to analyze the convergence of numerical solutions for linear, quadratic, and cubic loss of approximation of displacements. Calculations are carried out of the self-heating temperature in a trapezoidal shock absorber with a hole under complicated loading and also a shock absorber of AKS type. The effect of relaxation processes and geometrical dimensions on heating a solid cylindrical shock absorber is examined.Voroshilovgrad Agricultural Institute.
