Journal ArticleDOI
Thermodynamic and relaxation-based modeling of the interaction between martensitic phase transformations and plasticity
TL;DR: In this article, the authors focus on the issue of plasticity within the framework of a micromechanical model for single-crystal shape-memory alloys, and derive the Bain strain characterizing the transformation kinematics.
Journal ArticleDOI
A micromechanical model for martensitic phase‐transformations in shape‐memory alloys based on energy‐relaxation
Thorsten Bartel,Klaus Hackl +1 more
TL;DR: In this paper, a micromechanical model for single-crystalline materials undergoing diffusionless solid-to-solid phase transitions is developed based on the specification of laminated microstructures on the materials' microscale.
Journal ArticleDOI
On the thermomechanical coupling in dissipative materials: A variational approach for generalized standard materials
TL;DR: In this paper, a thermodynamically consistent framework is elaborated which indeed allows the realistic prediction of the temperature evolution, which is based on a fully three-dimensional, finite strain setting and it naturally covers coupled isotropic and kinematic hardening.
Journal ArticleDOI
Implementation of numerical integration schemes for the simulation of magnetic SMA constitutive response
TL;DR: This work establishes two algorithmic implementations of the internal variable model for MSMAs based on the numerical integration of the reorientation strain evolution equation and represents a classical predictor–corrector-type general return mapping algorithm.
Journal ArticleDOI
Towards the simulation of Selective Laser Melting processes via phase transformation models
TL;DR: A constitutive modelling framework stemming from phase transformations in shape memory alloys is adopted to the modelling of the changes of state during Selective Laser Melting, which serves as a basis for further enhancements such as the consideration of multiple solid phases of the underlying material.
