Conceptually, it consists of a set of Kelvin elements (spring and dashpot elements in parallel) connected in series.įor frequency-domain analyses, all of the viscoelasticity models ( Generalized Maxwell, Generalized Kelvin-Voigt, Maxwell, Kelvin-Voigt, Standard Linear Solid, and Burgers) have been augmented by a fractional derivative representation. The Generalized Kelvin-Voigt model has a Prony series representation with several time constants. The Maxwell material can be considered as a type of liquid, since its long-term deformation under a constant stress is unbounded. Two new viscoelasticity models have been added: Maxwell and Generalized Kelvin-Voigt.

To compute and identify the propagating modes, the Boundary Mode Analysis study is available in combination with the port conditions. The power of reflected and transmitted waves is available in postprocessing. The port condition supports S-parameter (scattering parameter) calculation, but it can also be used as a source to just excite a system. The combined setup with several Port conditions provides a superior nonreflecting condition for waveguides to a perfectly matched layer (PML) configuration or the Low-Reflecting Boundary feature, for example. Combining several Port conditions on the same boundary allows a consistent treatment of a mixture of propagating waves, for example, longitudinal, torsional, and transverse modes. A given Port condition supports one specific propagating mode. The new Port boundary condition, available with the Solid Mechanics interface, is designed to excite and absorb elastic waves that enter or leave solid waveguide structures.
