Rate Type Material Structure

Abstract

We assume that the deformations processes P∈π are piecewise continuously differentiable, i.e. for every time t∈[0,d_p] exist left and right derivatives $\frac{d}{{d\tau }}P(\tau )\left| {_{\tau = t}} \right. = \dot P(t)$ which are equal for all but a finite number of t∈[0,d_p].
