Proposed continuum model for simulating the behaviour of granular materials. (English) Zbl 0556.73002
The paper presents a possible way to simulate the very special behaviour of granular materials. Applying the well-known micro-elastic continuum theory to the problem a continuum theory with intrinsic volume-change was elaborated. The basic equations include the following unknown kinematic functions: the displacement vector and the intrinsic volume-change as a scalar function. The constitutive equation consists of six new elastic material constants, to evaluate them requires further investigations.
