Energy-based method for determination of allowable stress—Part I

Abstract

Energy parameters have been developed which enable consideration of plasticity, strain and low-temperature hardening of engineering materials when determining allowable stresses. Materials have been systematized according to their level of hardening and a universal diagram of material hardening has been constructed which allows one to work rationally towards the improvement of the basic mechanical properties of materials in order to increase the level of allowable (calculated) stresses using metallurgical and technological means.
