The Cauchy-Born stability criterion stipulate this Hessian matrix to be positive semi-definite. Solving the equations ruling the shift vector, enable to rule the shift vector out of the energy. The Cauchy-Born stability criterion for this homogenized energy renders the homogenized stability criterion....
one of which is similar to the "Argument Principle" in many modern textbooks on complex analysis. In modern control theory textbooks, the Cauchy argument principle is quite frequently used to derive the Nyquist stability criterion, which can be used to predict the stability of negative feed...

In a first step, one uses the uniform bounds and the Dunford-Pettis criterion to get weak compactness of the sequence of solutions in L1. This, combined with the renormalized formulation and averaging lemmas, implies the strong compactness of velocity-averages of fn. Since the operators L = ...

The method is based on the definition of a validity surface in the space of stress and the identification of those violated regions of the domain that do not satisfy the validity criterion at each step of the analysis. The stress of violated regions is corrected so that the stress over the...
