WebYou can now specify dynamic stiffness and damping characteristics of gasket elements modeled using the gasket behavior approach. The dynamic properties are expressed in terms of effective thickness-direction storage and loss moduli that can be specified as tabular functions of the excitation frequency and the level of preload. WebABAQUS/Standard always works in the global system when passing information to or from a user element. Therefore, the user element's stiffness, etc. should always be defined with respect to global directions at its nodes, even if local transformations (“Transformed coordinate systems,” Section 2.1.5) are applied to some of these nodes.
