Abstract
We consider a thermodynamic model for fatigue accumulation in an oscillating elastoplastic plate based on the two hypotheses that the fatigue accumulation rate is proportional to the plastic part of the dissipation rate and that the material can partially recover by the effect of melting. For the full model, consisting of the momentum and energy balances, an evolution equation for the fatigue rate and a differential inclusion for the phase dynamics, we prove existence of a solution in the given time interval.
Abstract (in Czech)
Uvažujeme termodynamický model pro akumulaci únavy v oscilujíci elastoplastické desce založený na dvou hypotézách, že míra akumulace únavy je přímo úměrná plastické části rychlosti disipace a že materiál se může částečně zotavit účinkem roztavení. Pro celý model, skládající se zákonů hybnosti a energie, evoluční rovnice pro míru únavy a diferenciální inkluze pro fázovou proměnnou, dokážeme existenci řešení v daném časovém intervalu.
