<FLOW> function

Description

This flow law is defined by a function which can be in terms of overstress \(f\) and cumulated plastic strain \(p\).

Syntax

The flow law will accept coefficients depending on the function. For example the above flow law will accept K, n, p as coefficients.

Example

A function such as a Norton law combined with cumulative plastic strain could be of interest:

(396)\[\dot{\lambda} = \left<\frac{f}{K}\right>^n\left(1-e^{p}\right)\]

This would result in the following syntax:

*flow function
  K 120.0
  n 5.0
  p 10.e-3
