Web17 de out. de 2024 · One of the most important parameters when setting up the Standard Contact is FKN value (Normal Penalty Stiffness). FKN controls contact penetration value, thus drastically influencing stresses in neighboring elements. FKN value is governing, e.g. if one of your plates in contact has stress higher than fy, simply rise FKN.
