Probing unknown welding parameters from convective heat transfer calculation and multivariable optimization
Amitava De,Tarasankar Debroy +1 more
TL;DR: In this article, a smart model that embodies an iterative procedure for the optimization of multiple unknown variables within the framework of phenomenological laws that govern heat transfer and fluid flow in the weld pool is developed.
Journal Article
Heat transfer and fluid flow during electron beam welding of 304L stainless steel alloy
TL;DR: In this article, a numerical model for three-dimensional heat transfer and fluid flow in keyhole mode electron beam welding was developed and applied to 304L stainless steel welds made at different power density distributions achieved by varying the focal spot radius at a fixed input power.
Journal ArticleDOI
Toward reliable calculations of heat and plastic flow during friction stir welding of Ti-6Al-4V alloy
TL;DR: In this paper, heat transfer and visco-plastic flow during friction stir welding of Ti-6Al-4V alloy were modeled in three dimensions by numerically solving the equations of conservation of mass, momentum and energy using temperature dependent thermo-physical properties and temperature and strain-rate dependent viscosity values.
Journal ArticleDOI
A perspective on residual stresses in welding
Amitava De,Tarasankar Debroy +1 more
TL;DR: In this article, the authors present recent research on calculation, measurement and alleviation of residual stresses in welding, including non-uniform simultaneous heating and cooling, local variation in shrinkage because of variable cooling rates in different regions of the weld, and strains associated with metallurgical phase transformations.
Journal ArticleDOI
Solidification Map of a Nickel-Base Alloy
TL;DR: In this article, an experimental and theoretical program of research is undertaken with the aim of developing a quantitative understanding of the solidification behavior under a wide range of temperature gradients and solidification growth rates.
