THERMAL-FORCE DEFORMATION OF A PHYSICALLY NONLINEAR THREE-LAYER STEPPED ROD

Consideration has been given to the thermal-force deformation of a three-layer plastoelastic rod with a stepped
thickness of one supporting layer. The physical equations of state are consistent with the Il′yushin theory of small
plastoelastic deformations. To describe the kinematics of a rod bundle nonsymmetric across the thickness, the authors
adopted the broken-normal hypotheses. A system of equilibrium equations has been derived, and its general iterative
solution in displacements has been obtained. A numerical parametric analysis of the rod′s stress–strain state has
been made.
