Mechanistic models of welding and 3D printing

 

 

Professor T. DebRoy

debroy@psu.edu

Process and product simulations - painless, insightful and fun

Learn about 3D printing/additive manufacturing - powder bed fusion, directed energy deposition and wire-arc processes.

Explore the practical and virtual worlds of welding - friction stir welding, conduction and keyhole mode laser welding, electron beam welding, gas-metal-arc and gas-tungsten-arc welding.

Examine heat transfer, fluid flow and mass transfer models, Monte Carlo simulations of grains structure and topology, genetic algorithm based optimization, models for phase transformation kinetics and reverse models that can switch traditional input and output variables.

Click on the animations, have fun and explore simulation results, or examine our reviews and theses for reusable insights. 

Contact us to schedule a demo of a model. The models can reduce the volume of trial and error testing, reduce defects and shorten time between the design and production. We collaborate with many companies and research groups worldwide.
