    Modeling the Droplet Impact on the Substrate with Surface Preparation in Thermal Spraying with SPH

    The properties of thermally sprayed coatings depend heavily on their microstructure. The microstructure is determined by the dynamics of the impact of the droplets on the substrate surface and the subsequent o...

    Simplified surface heat source distribution for GMAW process simulation based on the EDACC principle

    A simplified surface heat source for gas metal arc welding (GMAW) process simulation based on the principle of evaporation determined arc cathode coupling (EDACC) is presented. It allows for a simple implement...

    Concept for the calculation of the distribution of heat input in the cathode area by GMA welding

    Currently used approaches for the modeling of the heat input in gas metal arc (GMA) welding process simulation usually assume an axisymmetrical Gaussian distribution of heat flux in the cathode region. However...

    Effects of evaporation-determined model of arc-cathode coupling on weld pool formation in GMAW process simulation

    Currently used approaches for modeling the cathodic heat input in gas metal arc welding (GMAW) process simulation are usually based on very simplified approaches, either using a Rykalin-Rosenthal-distributed h...
