This study presents a new staggered coupled strategy to deal with thermomechanical
problems. The proposed strategy is based on the isothermal split methodology, ie the …

The model presented in this paper was shown to successfully account for cyclic loading
effects and thermomechanical coupling in SMAs, including the influence of load rate and …

This paper deals with the simulation of parametrized strongly-coupled multiphysics
problems. The proposed method is based on previous works on multiphysics problems …

Steel structures are designed to operate in an elastic domain, but sometimes plastic strains
induce damage and fracture. Besides experimental investigation, a phase-field damage …

In this article, we present a variational formulation for coupled problems in thermodynamics
the most suitable for long‐term simulations of plastic behavior. We start with three‐field Hu …

In practical applications, TiNi shape memory alloys (SMAs) exhibit behavior that can pose a
challenge with current constitutive models and their implementations in finite element …

Abstract Devices made of Shape-Memory Alloys (SMA) often exhibit a superelasticity or a
shape memory effect during the exploitation. Both effects include large deformations up to …

(1) The paper presents experimental and numerical results of the TiNi shape memory alloy
(SMA) subjected to a modified program of force-controlled tensile loading. The time …

This paper presents an investigation of thermomechanical effects related to the phenomena
of stress relaxation occurring in TiNi SMA subjected to modified program of displacement …

In this thesis, a novel approach is developed for visco-plasticity and nonlinear dynamics
problems. In particular, variational equations are elaborated following the Helligner …
