Multi-parameter generalization of nonextensive statistical mechanics
We show that the stochastic interpretation of Tsallis' thermostatistics given
recently by Beck [Phys. Rev. Lett {\bf 87}, 180601 (2001)] leads naturally to a
multi-parameter generalization. The resulting class of distributions is able to
fit experimental results which cannot be reproduced within the Boltzmann's or
Tsallis' formalism.Comment: ReVTex 4.0, 4 eps figure

Modeling Finite Deformation Behavior of Semicrystalline Polymers under Uniaxial Loading—Unloading
Strain localization in polyurethane foams. Experiments and theoretical model
none2Confined compression tests up to 70% of deformation have been performed on polyurethane foams. During these experiments strain localization has been observed (Pampolini et al. 2007-2).
This behavior is described by a one-dimensional model, in which the foam is represented as a chain of non-linear elastic springs with a double-well strain energy density, and the localization is attributed to progressive phase change.noneG.
