Web29 de mai. de 2024 · Results of load-displacement curve is affected by changing the Tangential behaviour, higher coefficient of friction giving much higher loading (which of course is not realistic). I've been using tangent coefficient of 0.1 for my analysis so far. I appreciate if someone give me some explanations how to specify friction for this case or … WebGeneral contact algorithm in Abaqus/Standard uses finite-sliding, surface-to-surface contact formulation by default. 3.5.1 Contact Discretization Abaqus/Standard uses conditional constraints to enforce contact between interacting surfaces. The location and conditions of these constraints may vary based on the type of contact discretization. In
