Mechanics of Solids

The method for solving the boundary value problem of the beam's creep and creep rupture strength condition of the pure bending based on the rod type structural model

E. V. Nebogina

Samara State Technical University, Samara, Russia

Abstract: The method for solving the boundary value problem of the beam's creep and creep rupture strength under condition of the pure bending based on the rod type structural model is proposed. Energy criterion of local element destruction is introduced. Comparative analysis of structural model calculated data and the quarter beam of D16T alloy at $T=250 ^\circ\mathrm C$ curvature value found by experiment is performed. Calculated data agree with those found by experiment. Correlation of the calculated data based on the proposed method with those based on phenomenological model of energy type creep is performed.

Keywords: creep, structural model, pure bending, material destruction, creep rupture strength
