- ESTIMATION OF DUCTILE FRACTURE BEHAVIOR INCORPORATING MATERIAL ANISOTROPY
vumat-old.f
- The model simulates transitional ductile to brittle fracture in steels using Rousselier s damage model for ductile fracture and the fracture stress (maximum principal stress) criterion for transganular cleavage.
ductile-fracture
- 在fortran环境下编写ductile_fracture子程序，可以通过MARC来调用，实现板材成形中破裂过程的可视化-Written in fortran environment ductile_fracture subroutines can be invoked by MARC, realized in sheet metal forming rupture process visualization
kgtn
- 用于ABAQUS软件的子程序，可对金属材料的韧性断裂行为进行精确的计算，并预测其断裂行为。(The subroutine for ABAQUS software can be used to calculate the ductile fracture behavior of metal materials accurately and predict the fracture behavior.)
Benzerga 1999
- Two types of coalescence models are compared: a localization-based model and plastic limit-load models.
benzerga 2004
- A theory of anisotropic ductile fracture is outlined and applied to predict failure in a low alloy steel. The theory accounts for initial anisotropy and microstructure evolution (plastic anisotropy, porosity, void shape, orientation and spacing) and
子程序
- 通过abaqus调用子程序模拟壳单元韧性断裂程序(Calling subroutine UMAT to simulate ductile fracture program of shell element)
