Thermomechanical coupling in shape memory alloys under cyclic loadings: Experimental analysis and constitutive modeling
Abstract In this paper, we examine the influence of thermomechanical coupling on the behavior of superelastic shape memory alloys subjected to cyclic loading at different loading rates. Special focusExpand

Structure and Magnetism in λ-MnO2. Geometric Frustration in a Defect Spinel
λ-MnO2, a metastable form of manganese dioxide, retains the cubic spinel structure upon lithium removal from LiMn2O4 by soft chemical methods, either electrochemical or acid leaching. The minimumExpand

A comprehensive approach for fatigue analysis of shape memory alloys
We develop a comprehensive approach for fatigue analysis of SMAs in three steps: first, the determination of the constitutive law allows the computation of the stabilized thermomechanical state ofExpand

Fibrillar structure and elasticity of hydrating collagen: a quantitative multiscale approach.
It is well known that hydration of collagenous tissues leads to their swelling, as well as to softening of their elastic behavior. However, it is much less clear which microstructural andExpand
