There is generally a relationship between these two force components. The relationship, known as the friction between the contacting bodies, is usually expressed in terms of the stresses at the interface of the bodies. The friction models available in ABAQUS: 当发生接触时，表面通常通过接触面传播剪力和法向力。这两种力之间一般有关系。该关系也叫接触体间的摩擦，它一般表达为物体接触面应力的形式。在ABAQUS 中的摩擦模型： • include the classical isotropic Coulomb friction model (see “Coulomb friction,” Section 5.2.3 of the ABAQUS Theory Manual ), which in ABAQUS: • 包括经典的各向同性库仑摩擦模型（见“Coulomb friction,” Section 5.2.3 of the ABAQUS Theory Manual），该模型在 ABAQUS 中： in its general form allows the friction coefficient to be defined in terms of slip rate, contact pressure, average surface temperature at the contact point, and field variables; and 普通式允许根据滑移率，接触压力，接触点的平均表面温度和场变量定义摩擦系数； provides the option for you to define a static and a kinetic friction coefficient with a smooth transition zone defined by an exponential curve; 提供选项来定义静止和运动学的摩擦系数用由指数曲线定义的平滑转换区； • allow the introduction of a shear stress limit, , which is the maximum value of shear stress that can be carried by t...
