ABAQUS 磨损子程序代码

以下是一个简单的ABAQUS磨损子程序代码示例：

*HEADING
** This is an ABAQUS user subroutine for wear prediction.
*NODE
** Define the nodes where the wear occurs.
*NSET, NSET=WEAR_NODES
1, 2, 3, ..., n
** Define the sliding surface elements.
*ELSET, ELSET=SLIDING_SURFACE
1, 2, 3, ..., m
** Define the wear surface elements.
*ELSET, ELSET=WEAR_SURFACE
m+1, m+2, ..., p
*INITIAL CONDITIONS, TYPE=TEMPERATURE
** Define the initial temperature of the wear surface.
WEAR_SURFACE, 20.0
*USER MATERIAL, CONSTANTS=6
** Define the wear material properties.
10.0, 0.3, 0.5, 0.1, 0.2, 0.0
*USER SUBROUTINE, DLL='wear.dll', VERSION=1.0
** Call the wear subroutine.
*END STEP

这里，`WEAR_NODES`是磨损模型中的节点，`SLIDING_SURFACE`是滑动表面元素，`WEAR_SURFACE`是磨损表面元素。`WEAR_SURFACE`的初始温度为20摄氏度。`USER MATERIAL`定义了磨损材料的特性，其中包括杨氏模量、泊松比等。最后，`USER SUBROUTINE`调用磨损子程序。
