Contact element

In the 3D solids Ramseries can perform an Contact-Impact analysis between bodies.

To model Contact-Impact between bodies using Ramseries, it’s necessary to create the geometry of each body and indicate the potential contact areas. To define such contacts, Ramseries has two options:

1-) Utilize the menu options Geometry\Create\Contact_Surface and Geometry\Create\Contact\Volume to create contact between lines and surfaces, respectively. This option allows to automatically generating contact elements that join the nodes of the impact bodies. Nonetheless, it can only be used when the two surfaces or volumes to connect are homogeneous.

2-) Connect explicitly the potential points of contact starting from lines. This option is very useful when it’s known beforehand the potential nodes to be in contact.

With the condition Contact can be indicated which are the contact elements between bodies. This condition can be applied to lines,surfaces or volumes.

Penalty indicates the stiffness of the contact element.
