| void nlstresses | ( | long | ipp, | |
| long | im, | |||
| long | ido | |||
| ) |
function computes nodal forces in contact problems nodal forces are computed from difference of nodal displacements at appropriate nodes the name nlstresses is used only with respect to other "classical" material models which work with stresses
| ipp | - integration point id | |
| im | - index of material type | |
| ido | - index in array other |
