网页A contact interaction property can be referred to by a general contact, surface-to-surface contact, or self-contact interaction. For more information, see About mechanical contact properties, Thermal contact properties, and Electrical contact properties.
15.13.1 Defining a contact interaction property
网页A contact interaction property can be referred to by a general contact, surface-to-surface contact, or self-contact interaction. For more information, see Mechanical contact properties: overview, Section 30.1.1 of the ABAQUS Analysis User's Manual, and Thermal contact properties, Section 30.2.1 of the ABAQUS Analysis User's Manual.
29.3.3 Contact properties for general contact
网页The default contact property model in ABAQUS/Explicit assumes “hard” contact in the normal direction, no friction, no thermal interactions, etc. You can assign a nondefault contact property definition (surface interaction) to …
About contact interactions - Massachusetts Institute of Technology
网页Contact properties. Contact interactions in a model can refer to a contact property definition, in much the same way that elements refer to an element property definition. By default, the surfaces interact (have constraints) only …
Assigning contact properties for general contact in Abaqus/Explicit
网页You can assign a nondefault contact property definition (surface interaction) to specified regions of the general contact domain. Contact property assignments propagate through all analysis steps in which the general contact interaction is active.
ABAQUS接触分析详解——接触属性 - 知乎 - 知乎专栏
网页ABAQUS中的摩擦通过经典的库伦摩擦进行计算，计算的摩擦力为接触界面间允许滑动的最大剪应力，如下所示。 根据摩擦系数的不同取值方式以及应用场景的不同，又可分为以下几类接触行为。 1. 默认条件下，摩擦系数为定值，剪切力与摩擦系数成正比，如图4所示。 图4 剪切力与接触压力关系图. 2. 静动衰减系数. 摩擦系数由静摩擦系数向动摩擦系数成指数过渡，如图5所示4，可通过实验测试数据的方式进行模拟。 图5 静动衰减系数. 3. 粗糙. 摩擦 …
网页Contact properties for contacting surface(s) are analogous to element property in used in Abaqus. By default, the surfaces interact only in normal direction to resist penetration, however depending on the
ABAQUS中的接触简介 - 知乎 - 知乎专栏
网页ABAQUS/Standard使用Newton-Raphson算法来求解非线性问题，它把分析过程划分为一系列的载荷增量步，在每个增量步内进行多次的迭代，得到合理的解后，再求解下一个增量步，所有增量响应的总和就是非线性分析的近似解。 ABAQUS/Explicit 在求解非线性问题时不需要进行迭代，而是显式地从上一个增量步的静力学状态来推出动力学平衡方程的解。 Explicit 的求解过程需要大量的增量步，但是由于不进行迭代，不需要求解全体方程组，每 …
ABAQUS中接触设置小问题总结 - 技术邻
网页接触属性（CONTACT PROPERTY） 包括两部分：接触面之间的法向作用和切向作用。 对于法向作用，ABAQUS中接触压力和间隙的默认关系是“硬接触”（HARD CONTACT）。 硬接触：接触面之间能够传递的接触压力大小不受限制；当接触压力变为零或负值时，两个接触分离，并且去掉相应节点上的接触约束。 对于切向作用，ABAQUS中常用的摩擦模型为库仑摩擦，即使用摩擦系数来表示接触之间的摩擦特性。 默认的摩擦系数为零，即无摩擦。 库 …
Contact cohesive behavior - Massachusetts Institute of Technology
网页General contact in Abaqus/Explicit and contact pairs in Abaqus/Standard optionally support each slave node associated with interactions that are assigned a cohesive property to become bonded once (either initially or during a simulation). Simulation results with this option can be highly sensitive to the assignment of slave and master roles ...
