Abstract:

Thermomechanical behavior of inhomogeneous viscoplastic structures under cyclic loading is investigated for the problem of harmonic bending and dissipative heating of a three layer beam. Two problem statements are used. One is based on the generalized thermomechanically consistent flow theory (complete problem statement) and the other one is the approximate scleronomic model implementation (approximate problem statement). Aluminium alloy and steel are chosen as the materials of layers. Comparison of the results obtained for complete and approximate problem statements is performed. Comparative estimation of beam loss coefficients for different configurations is also performed.
