 An evolution function must be associated to ''PEN_NORMALE'' and/or ''PEN_TANGENT'' (depending on generalized displacements GD). These function can be different.
+===== AdhesiveStickingContactMaterial =====
+=== Description ===
+Adhesive sticking contact is a sticking Contact material that is initialized with an unilateral type of contact (positive or negative) and that each slave node where contact is detected becomes bilateral (adhesive behavior).
+Up to now, forces are computed forces are computed as classical sticking depending to Normal and Tangential Penalty.
