Traditionally, multi-physics/phase simulation software programs lack tools for uncertainty quantification and optimization. More recently, there is a growing body of research that has integrated these tools into multi-physics/phase simulation software programs [1-4]. Building on this methodology, the study integrated open-source software programs, OpenFOAM [5] for multi-physics/phase simulations and DAKOTA [6] for optimization and uncertainty quantification. Furthermore, the coupled software was successfully applied to benchmarks. The overarching goal was to develop an open-source framework for multi-physics/phase simulations, optimization and uncertainty quantification. The applications of this open-source framework span several industries ranging from aerospace and energy to healthcare and manufacturing.

Stress triaxiality is one of the most important factors that controls fracture ductility. The objective of this study was to investigate the influence of stress triaxiality on fracture ductility for specimens’ printed using stereolithography (SL). Dog bone shape specimens were printed using Formlabs® Form 2 Desktop SLA 3D printer. The specimens were built layer by layer with the help of this 3D printer. Each layer of liquid photopolymer is solidified through a computer-controlled ultraviolet (UV) light source with a laser spot size of 140 𝜇m. A photopolymer resin supplied by the manufacturer which comprised of a proprietary mix of Methacrylated …
