Influence of Hardening and Inhomogeneity on Internal Loops in Pseudoelasticity
ZAMM, 2000This paper is devoted to mathematical modeling of hysteretic behavior exibited by shape memory alloys in the pseudoelastic temperature range. The quasistatic phase transformations are considered, which occur at a constant temperature above the austenite finish temperature.

The pseudoelasticity of a Ni45Ti50Cu5 alloy
2000Since several years the Ni(50-X)Ti50CuX alloys are attentively considered for the interesting features related to the B2-->B19' transformation involved in the pseudoelastic behavior. In contrast with the binary NiTi, where two martensitic transformations, B2-->R-phase and R-phase-->B19' can overlap, in the ternary alloy a single transformation is ...

A two‐invariant pseudoelastic model for reservoir compaction
International Journal for Numerical and Analytical Methods in Geomechanics, 2017SummaryPredicting the deformations of deep reservoirs due to fluid withdrawal/injection is a challenging task that could have important environmental, social, and economical impacts. Finite element models, if endowed with an appropriate constitutive law, represent a useful tool for computing the displacements, the deformations, and the stress ...

Processing and surface treatments for pseudoelastic wires and strands
Materials and Manufacturing Processes, 2016The aim of this work is a preliminary investigation of the manufacturing process of Ni-Ti and Ni-Ti-Cr wires and strands to be applied in mechanical applications. The diamond wires for stone cutting were used as a case study. A prototype of multi-wire Ni-Ti strand has been prepared, characterized and thermally treated in this research.

Reorientation mechanisms and pseudoelasticity in iron nanowires
Journal of Physics D: Applied Physics, 2011Using molecular dynamics simulations we present the ⟨1 1 0⟩ → ⟨0 0 1⟩ reorientation and pseudoelasticity induced by axial strain in iron nanowires. The reorientation mechanism shows an intricate dependence on the deformation temperature. Specifically, the original ⟨1 1 0⟩ nanowires and the reorientated ⟨0 0 1⟩ counterparts exhibit pseudoelastic ...

An Evaluation of Pseudoelastic Descriptors Used in Arterial Mechanics
Journal of Biomechanical Engineering, 1999Understanding how transmural distributions of stress relate to the mechanisms of vascular growth, remodeling, and disease necessitates computations that are based on a constitutive relation for the arterial wall. Although a number of candidate relations are in the literature, they have not been compared in detail.
