Study on Materials Flow Destruction Causes to the Shape Change with New Method of Proving a Specific Energy Theory

Abstract:

The three principal stresses of unit body correspond to the three circles of stress. Each circle of stress corresponds to one of the biggest shear stresses. Each of the biggest shear stresses corresponds to a shear stress’s specific energy. Therefore, specific energy of unit body is solved. It is compared with specific energy of shear stress, staying a dimensional state of stresses with materials flow destruction. And people can get a common formula about specific energy theory of the shape change during the engineering design. The new method’s proving process is very simple, and the nature of failure mechanism is clearer.
