摘要： 本文从广义Mises屈服准则出发,建立了一个新的复合型断裂判据—广义塑性区尺寸因子判据。通过选择判据中的参变数α,可望得到与工程实际更加相符的断裂判据。该判据还可用来求解三维裂纹问题。
Abstract: Based on the generalized Mises yield criterion, a new combined type of fracture criterion is established which is called the generalized plastic-region size factor fracture criterion. By altering the value of parameter a, we may obtain fracture criteria which are more coincident with the engineering practice. The criterion can be also used to solve three-dimensional crack problems.
