Constitutive laws

This page should grow to give overview of all constitutive laws in Yade. The purpose is twofold:

  1. Names of respective classes do not say much and it seems that lot of code is duplicated; should improve orientation in material models available
  2. Not all laws are in the same development stage. Some of them are well validated while others are purely experimental. Users should quickly find out which ones are safe to use in this table.

Yade users are strongly encouraged to choose one of the green laws unless a reason exist to decide otherwise.
