[ABAQUS] *MPC 중 SLIDER의 사용

[Brian Lee]

Using MPC type SLIDER

MPC type SLIDER keeps a node on a straight line defined by two other nodes but allows the possibility of moving along the line and allows the line to change length.

When transitioning from multiple layers of solid elements to shells, it is often desirable to constrain the nodes on the free edge of the solid elements to remain in a straight line. (This constraint is consistent with shell theory.) The SLIDER MPC can perform this function without restraining the “thinning” behavior of the solid layers. The SS LINEAR MPC is then used to attach the shell element to this edge.

In ABAQUS/Standard when a SLIDER MPC is used with one of the shell-solid MPCs—SS LINEAR, SS BILINEAR, or SSF BILINEAR—it must be given following the shell-solid MPCs.

Input data

For each node shown in Figure 20.2.2–14 and Figure 20.2.2–15, give the nodes , , and for each line of nodes that should remain straight. For each node shown in Figure 20.2.2–14, give the nodes , , and , and so on for each line of nodes that should remain straight.
