Numerical Algorithm to Perform Viscoelastic Analysis

Viscous materials exhibit both viscous and elastic characteristics when undergoing deformation. The response of such materials to force is characterized by two distinct phases. The materials first deform instantaneously akin to elastic materials. Following on, the material continues to deform at a relatively slower time scale. Typically, materials undergoing thermal treatment exhibit viscoelastic properties.

The past several years has seen a fast deployment of wide-bandgap power devices in fast chargers, electric vehicles, data centers and renewable energy processing. The performance of power devices is fast progressing towards their intrinsic material limit. As these devices can handle higher voltage and larger current density, packaging and thermal management will become the key limiting factor for exploiting their benefits in power electronic converters and systems.
