Abstract: | A finite-element algorithm is proposed for the analysis of the thermoviscoelastoplastic stress-strain state of bodies under
complex loading (thermal and mechanical). It is assumed that an arbitrary element of the body deforms along a rectilinear
or slightly curved path. The three-dimensional stress-strain state of the body’s elements is determined using the iterative
method of additional strains. The technique is tested by analyzing the three-dimensional viscoelastic stress-strain state
of a hollow cylinder and the thermoplastic state of a disk
