Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables
1 Introduction The mechanics of materials is an important and active research field of continuum mechanics for solids. Here, the main question is the formulation of constitutive equations, most importantly, the derivation of stress/strain relations for new materials. Examples are viscous and plastic deformations, or combinations thereof, phase transformations, softening phenomena, that is, damage modeling, and others.
