22.1.4 - Frictional - behavior - - 摩擦行为(7)

considered when determining friction properties that depend on these variables.

温度和场变量分布于梁和壳单元能一般的包括单元截面的梯度。这些单元间的接触发生在参考面，因此，当决定摩擦属性依赖这些变量时，不考虑单元中的温度和场变量梯度

Surface interaction variables related to friction 涉及摩擦的面相互作用变量

ABAQUS provides output of the shear stresses at each slave node that uses a surface interaction model containing frictional properties. The shear stresses, CSHEAR1 and CSHEAR2, are given in the two orthogonal slip directions, which are constructed on the master surface (see “Contact formulation for ABAQUS/Standard contact pairs,” Section 21.2.2). There is only one slip direction in two-dimensional problems. Details about how to request contact surface variable output are given in “Defining contact pairs in ABAQUS/Standard,” Section 21.2.1, and “Defining contact pairs in ABAQUS/Explicit,” Section 21.4.1.

Contour plots of these variables can also be plotted in ABAQUS/CAE. ABAQUS提供输出每个包括了接触属性的表面相互作用的从面节点的剪应力。在两个正交滑移方向给出剪应力CSHEAR1和CSHEAR2，这两个方向在主面上构造（见“Contact formulation for ABAQUS/Standard contact pairs,” Section 21.2.2）。在二维问题中只有一个滑移方向。要求输出接触面变量的细节见“Defining contact pairs in ABAQUS/Standard,” Section 21.2.1, and “Defining contact pairs in ABAQUS/Explicit,” Section 21.4.1。 ABAQUS/CAE里可以为这些变量画等高线图。 Additional reference
