可以把一个实体或者实体的一部分定义为rigid body 可以赋予大多数单元类型 优势:只计算ref node上的6个dof ,所以计算成本低。A. finite elementabaqus 有庞大的单元类型库,并且abaqus /explicit的单元库是abaqus/standard 的子集。DOF of Elem不同的单元类型有不同的自由度,如:stress/displacement analysis的单元为tr...
Reference point是刚体的参考点,可以点击后面的箭头在图中选择参考点,注意:如果将后面的 adjust poi nt to center of mass at start of an alysis选中则选择的是刚体质心位置!销节点与捆绑节点的区别:RegionRegion typetypeRegionRegionBodyBody Celements)Celements)(None(NonePinPin (nodet)(nodet)(None)(None...
Abaqus/Standard and Abaqus/Explicit activate only those degrees of freedom needed at a node. Thus, some of the degrees of freedom listed above may not be used at all nodes in a model, because each element type uses only those degrees of freedom that are relevant. For example, two-dimension...
7123 nodes are used more than once as a slave node in *TIE keyword.One of the *TIE constraints at each of these Nodes have been identified in node set WarNodeOverconTieSlave When defining contact, common nodes repeat the definition several times, this may be over constrained problems (may...

point, which can be difficult to obtain and characterize in the presence of material nonlinearity, since FEAMAC provides the effective, evolving composite response at each integration point (accounting for lower-scale inelastic and damage mechanisms and the resulting local redistribution of stress). ...
Each row of the table corresponds to a slave node in node set SNODES. The first column of the table identifies the slave node for that row. Because this is a mechanical contact simulation, the second column specifies the contact status at the slave node. Since the contact property ...
