Experimental Investigation and Numerical Analysis of

Aug 24, 2016 · To better understand mechanical ruling process of diffraction gratings, a 3D thermomechanical-coupled FE model was developed in DEFORM ® to predict the deformation and temperature fields. The material constitutive model of strain-gradient plasticity was used in this FE analysis to study the size effect of the micron-scale groove-forming process. Finite Element Simulation and Experimental Validation of Jan 01, 2018 · Numerical Modeling Simulation of laser assisted machining was conducted in two steps:Thermal simulation for laser heat source and coupled thermo-mechanical cutting simulation. Both steps were sequentially coupled. Thermal modelling was done first to get temperature distribution in the workpiece due to moving laser heat source.

Metallo-Thermo-Mechanical Coupled Process Modeling

This work is concerned with prediction of the phase change effect on orthogonal cutting of AISI 1045 steel based on a true metallo-thermo-mechanical coupled analysis. A metallo-thermo-mechanical coupled material model is developed, and a finite element model is used to solve the evolution of phase constituents, cutting temperature, chip morphology, and cutting force simultaneously using ABAQUS.

Recent Advances in Thermal Mechanically Coupled

coupled thermal-mechanical analysis is performed to incorporate the effects of the cure kinematics on the thermal and structural behavior. To perform such an analysis one is required to have a good knowledge of the temperature dependent thermal and structural properties.Thermo-Mechanical Coupled Analysis of Laser-Assisted Jan 30, 2021 · Thermo-mechanical coupled analysis of laser-assisted mechanical micromilling of difficult-to-machine metal alloys used for bio-implant / Ninggang Shen, Hongtao Ding (xsd:string) dc:subject:Biomedical implant materials (xsd:string) Coupled thermo-mechanical analysis (xsd:string)
