Ultimate load analysis of strength-differential discs fixed on periphery

摘要

Some useful metals in engineering have strength-difference effect. Most of strength-differential materials can be approximately simplified for linearly elastic-perfectly plastic modals with strength-difference effect. In this paper, Mohr yield criterion is used to analyze the ultimate load of a strength-differential disc fixed on periphery. It is proved that the strength-difference effect of material evidently affect the ultimate load of the disc fixed on periphery. Considering the strength-difference effect of material, the analysis consequence of this paper is of general significance.
