This is really meant for static analyses, to prevent rigid-body motion when the contact detection fails between a contact pair. In static models with force loading, the contact stiffness may not be sufficient to enforce the contact constraint and as a result one part may glide through the other which results in rigid body motion. Using contact stabilization in such cases introduces some artificial stiffness to make the contact detection robust. Although it’s called “stabilization damping”, it’s really like weak springs for open contact. Based on the pseudo-time increment, it provides a stiffness term – the documentation and name say “damping”, but this is to help visualize what the associated restoring force would be in a given time increment.<\/p>\n","protected":false},"template":"","class_list":["post-162175","topic","type-topic","status-publish","hentry","topic-tag-4391","topic-tag-contact","topic-tag-convergence","topic-tag-damping","topic-tag-mechanical","topic-tag-modeling-and-meshing","topic-tag-stabilization","topic-tag-static","topic-tag-structural-and-thermal","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
