How to specify Sticking and Sliding conditions for Contact between two bodies?
‘Mu’ – Friction coefficient and TAUMAX are the two inputs user needs to specify. If Ft >= Mu*Fn where Fn –> Normal Force & Ft –> Tangential Force, the bodies slide relative to each opther and the two contacting bodies experince a Shear force of TAUMAX. Sticking happens when Ft < Mu*Fn Return to Top 44. How to estimate TAUMAX? TAUMAX = (Von Mises Yield Stress/1.732) This is an empirical formula Return to Top 45. I have Higher order elements (with mid-side nodes) on the two contacting surfaces & I want to analyse the problem using NTN Contact. Can I create NTN Contact between the mid-side Nodes? Due to the uneven nature of the kinematically consistent reaction forces at the nodes of midside-noded elements, NTN contact should NOT be applied to mid-side nodes. In effect, usage of NTN implies that only lower order elements be used for underlying mesh of contacting parts. Return to Top 46. While editing the real constants of a Contact element, like FKN can negative values be entered? In th
