New applications of conjugated strength criterion

Abstract

This article describes experimental results under combined loading of specimens manufactured from construction steel 11523. Specimens were loaded by amplitude of the torque, then by combination of torque and tension prestress. For evaluation of the results the conjugated strength criterion was applied. Further, another approximation based on the same boundary conditions as the described conjugated strength criterion was proposed. The performed experiments and their results embody a good agreement with bellow mentioned conjugated strength criterion. The experiments were performed on modified testing machine.
