STOP

STOP, stop_name, type, body_nr, mat_nr, layer_nr, xc, yc, xt, yt, height/radius, length, kn, d_fact;

Creates a stopper element to limit the in-plane travel range

  • Creates a contact element between a movable contact and a fixed target node. The contact node is defined by the xc- and yc-coordinates and the target node by the xt- and yt-coordinates.
  • The stopper limits the travel range in the direction from the contact to the target node. Tangential motion components (slide motion) are not restricted.
  • The movable contact domain is either represented by a rectangular or a circular stopper with the center at the contact node position.
  • The default contact stiffness and damping factor can be overwritten by the kn- and d_fact-parameters. The travel range between contact nodes and target nodes will be reduced by the stopper size defined by the height/radius-parameter.

Input Data⚓︎

Parameter Description
stop_name Reference name of the primitive (can be empty)
→ Alphanumeric name, has to start with a letter
type Type of the stopper element
rect → Creates a rectangular stopper element
circ → Creates a circular stopper element
body_nr Reference number of related mass body
→ > 0, the contact is related to the specified mass body
mat_nr Reference number of the material properties
→ Use existing material properties only (see MATP command)
layer_nr Layer number (the current version supports only one layer)
→ If empty, the primitive is part of the first layer
xc X-coordinate of the movable contact node
yc Y-coordinate of the movable contact node
xt X-coordinate of the fixed target node
yt Y-coordinate of the fixed target node
height/radius First dimensional parameter of the contact domain
→ rect - Height of the rectangular stopper element
→ circ - Radius of the circular stopper element
length Second dimensional parameter of the contact domain
→ rect - Length of the rectangular stopper element
→ circ - Unused
kn Contact stiffness
→ If empty, use the default contact stiffness
d_fact Contact damping factor
→ If empty, use the default contact damping factor
