Modeling of pressure induced magnetic and magnetocaloric effects in dissipative magnetic shape memory alloy systems

This article presents a coupled magneto-thermo-mechanical model of pressure-dependent Magneto-caloric Effect (MCE) and magnetization responses for polycrystalline Magnetic Shape Memory Alloys (MSMA). Coupled constitutive equations are derived from a Helmholtz free energy function in a consistent thermodynamic way. The hysteretic and dissipative characteristics of phase transformations in MSMAs are captured by the internal state variables approach with their evolution equations. The model is calibrated and validated with the existing experimental data. The validated constitutive model is then exploited to predict MCEs at different pressures and magnetic field levels. Some predicted results are compared with the available experimental data., , , # Modeling of pressure-induced magnetic and magnetocaloric effects in dissipative magnetic shape memory alloy systems

This repository contains the dataset and code used for simulations presented in the paper \"Modeling of pressure-induced magnetic and magnetocaloric effects in dissipative magnetic shape memory alloy systems,\" which has been accepted in Proceeding of Royal Society A under paper ID RSPA-2023-0241. The project aims to simulate the magnetostructural transition (first-order) and pure phase transition (second-order) in magnetic shape memory alloys. Additionally, a continuum model has been developed to capture adiabatic temperature change and isentropic entropy during the heating and cooling of ma...
