On Necessary and Sufficient Conditions for Wedging in Two Contact Node System
A necessary and sufficient condition for wedging in two node system is explored. When external loading is zero, wedging is possible if and only if the constraint vectors consisting of contact stiffness and coefficient of friction, directing either admissible or inadmissible region, are positive linear dependent. This condition is validated by comparing with the conventional necessary condition.
