Many real-life signals and, in particular, in the space physics domain, exhibit variations acrossdifferent temporal scales. Hence, their statistical momenta may depend on the time scale at which the signal is studied. To...

A simple and robust nonlinear dilatation constitutive model with clear mechanics concept is introduced, and the stiffness coefficient matrix of constitutive relationship is presented. A kind of coarsed-grained soil is co...

Based on the concept of true stress and the strain equivalence hypothesis, a three-dimension elastic-plastic damage constitutive model for rock is established. Combining the nonlinear unified strength model as the yield ...
