johnsoncook的模型属性推导及umat子程序中定义材料属性的教学，对于Fortran语言在ABAQUS中的使用很有帮助(Johnson cook's derivation of model properties and the teaching of defining material properties in UMAT subroutine are very helpful for the use of FORTRAN language in ABAQUS)

在abaqus软件中输出应力三轴度和罗德角，使用的uvarm子程序编写的，程序较为简单(In ABAQUS software, the stress triaxiality and Rhode angle are output, which is written by uvarm subroutine, and the program is relatively simple)

可以快速精确地模拟结构的单调滞回试验结果，计算速度比实体快得多，效果也好
