NODE-BASED SURFACE 基于点的表面/学习整理
本帖最后由 wrj001 于 2021-8-15 21:06 编辑Overview
A node-based “surface”:
[*]can be used only as a “slave surface” in contact calculations;
[*]can be used as a “slave” or “master surface” in a surface-based tie constraint;
[*]is convenient in three-dimensional cases where Abaqus cannot construct a unique physical surface on the elements, such as a pipe modeled with pipe elements contacting the ocean floor or cables modeled with trusses contacting the ground after they break;
[*]Others
Creating a node-based surfaceYou create a node-based surface by specifying the nodes or node sets that form the surface.
You must assign a name to the node-based surface; this name will be used when defining contact interactions that involve the surface.
An optional associated area can be defined for each node. If no area is defined for a node and the surface is defined in a contact pair, the area specified as part of the contact property definition is used. If no area is specified as part of the contact property definition, a unit area is used.
