Simulation of Laser Powder-bed Fusion Additive Manufacturing Process Using the COMSOL Multiphysics® software
Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... Read More
Acoustic Upside-Down Levitator with a Solid Sample
Introduction: Acoustic levitators are used to levitate small samples (ca. 0.01 - 6 mm) at a stable position in a gas or liquid environment. Acoustic levitators were first developed und used for experiments in space (1970s, by NASA / ESA), the application later became terrestrial (1990s). ... Read More
Phase Field Modeling of Phase Separation and Dendrite Growth
A large variety of applications in environmental, petroleum and chemical engineering involve multiphase flow. Examples include fluid flow in presence of bubbles/droplets, phase separation of immiscible fluids and wetting phenomena. Multiphase flow is characterised by the presence of an ... Read More
Free Surface Deformation of the Weld Pool in Orbital Narrow Gap GTA Welding
Arc current welding is a widespread process in heavy industry for the assembly of metallic components. In order to ensure the good quality of assemblies welds, it is appropriate to master the welding process but also to have a deep understanding of interactions with the weld pool and ... Read More
Mechanical Damage Models for Concrete
Damage models can be used to simulate the quasi-brittle behaviour of cementitious materials, since they can represent cracking in a smeared-way under various loading conditions. COMSOL Multiphysics® developed a functionality to access external material models for structural mechanics in ... Read More
