H-M Method for calculating the fracture curve based on modified the H-M model

摘要

The breaking curve calculation method according to the present invention is characterized in that the breaking curve calculation method according to the present invention includes the steps of obtaining the triaxial stress and strain at the center portion of the standard tensile specimen at the breaking point of the standard tensile specimen without the notch, Calculating a constant? Value by substituting the triaxial stress and strain obtained in the above step into the following equation (1); And substituting the constant? Calculated in the above step into the following equation (2) to obtain a fracture curve. ... (1) ... (2)
