Abstract:
The process of softening and destructions of material is investigated at creep under complex tense state conditions on the basis of a structural model. Energy criterion of local element destruction is presented. Comparative analysis is performed of structural model calculation data and experimental data on the protracted durability for thin-shelled tubular steel standards 12X18H10T at $T=850\,^\circ \rm C$ for the followings types of tense state: tension, twisting and tension, intrinsic pressure and tension. Calculation results are compared with analogical data of the existing phenomenological creep and protracted durability models.
Keywords:
creep, structural model, combined stress conditions, material softening, material destruction, stress-rupture strength.
