WebbConstraints between nodes and surfaces. 4. Contact type 8: nodes spotwelded to surface. Slave nodes are tied to the masters until a failure criterion is reached. Thereafter they can slide on or separate from the masters as in a type 5 contact surface. This type of surface can be used to represent spot-welded or bolted connections. Webb17 mars 2024 · I used Tied-Node-to-Surface for both, the contact between the core SPH and the transition part and between the transition part and the outer finite elements. The Non-Reflecting-Boundary-Condition was also applied on the outer segments of the outer finite elements. it is working now somehow.

Webb26 okt. 2024 · I used Tiebreak Surface to Surface to provide this connection between the plate and the solid element. So, I selected the top surface of the plate as the slave segment and the bottom surface of the solid element as the master segment. The connection area is 200 in^2, so setting the shear stress failure (SFLS) less than 100,000 Ib/200 in^2 = 500 ... WebbFigure 3 shows how the contact behaves when the first two criteria are met, but the third is not. Figure 3: node to surface, slave surface is smaller and has higher element density than master.
