Contact Laws

Introduction

NairnMPM and OSParticulas implement contact physics on crack surfaces and between materials in multimaterial mode by using contact laws. Each contact law can define frictional contact or describe an imperfect interface. Contact laws are assigned to crack or material surfaces by using the ContactCracks or ContactMM commands, by using the Contact material property, or by choosing a custom contact law in the NewCrack command. This section explains the p]]ossible contact laws.

You create materials using a Material command block. Within that block all material properties are set using property commands. Refer to each material type to learn about its possible properties.
