On the stored and dissipated energies in heterogeneous rate-independent systems. Theory and simple examples.

Abstract : The aim of the present work is to determine the amount of dissipated and stored energies in structures containing frictional cracks and elasto-plastic zones. The proposed theory combines micromechanical and thermodynamic tools to calculate both energies. Using simple examples, it is shown that the Taylor-Quinney coefficient is not a constant, and can be much less than the values usually considered (i.e., close to unity).
