+# Abaqus Contact Property Models
+
+## Definition
+
+Abaqus contact property models define the normal, tangential, thermal, electrical, pore-fluid, and user-defined behavior of interacting surfaces.
+
+## How They Work
+
+By default, contact resists penetration in the normal direction. A contact property can add hard or softened pressure-overclosure behavior, contact damping, friction, user-defined interfacial constitutive behavior, breakable bonds, pressure penetration, surface-based cohesive behavior, thermal conductance, heat generation, electrical conductance, or pore-fluid transfer.
+
+The contact property is assigned to a contact pair or to a region of a general contact domain. This separates the geometric contact definition from the interface law.
+
+## Why It Matters
+
+The contact surfaces determine where interaction can occur; the contact property determines what interaction means physically. Friction, damping, cohesive behavior, and coupled-field transfer can dominate nonlinear response.

+- [[Finite Element Contact Formulation]] gives the contact constraint context.
+- [[Abaqus Contact Interaction Definition]] defines the surfaces or domain to which properties are assigned.
+- [[Abaqus Contact Formulations and Enforcement]] determines how the property is enforced numerically.
+- [[Abaqus Cohesive and Gasket Elements]] is the element-based interface alternative to surface-based cohesive behavior.
