Residual Stresses Control in Additive Manufacturing
Journal of Manufacturing and Materials Processing, 2021 Residual stresses are one of the primary causes for the failure of parts or systems in metal additive manufacturing (AM), since they easily induce crack propagation and structural distortion.

Numerical Simulation of a High-Speed Impact of Metal Plates Using a Three-Fluid Model
Metals, 2021 The process of wave formation at the contact boundary of colliding metal plates is a fundamental basis of explosive welding technology. In this case, the metals are in a pseudo-liquid state at the initial stages of the process, and from a mathematical ...

A mixed distribution to fix the threshold for Peak-Over-Threshold wave height estimation
Scientific Reports, 2022 Modelling extreme values distributions, such as wave height time series where the higher waves are much less frequent than the lower ones, has been tackled from the point of view of the Peak-Over-Threshold (POT) methodologies, where modelling is based on

Topology optimization of impeller blades in baffled stirred tanks
Case Studies in Chemical and Environmental Engineering, 2020 An approach for the numerical topology optimization of baffled stirred tanks is presented and demonstrated exemplarily on impeller blades. The methodology is based on the well-known Brinkman penalization method, which is used to alter the impeller blade ...

Numerical Modelling of Microstructure Evolution in Friction Stir Welding (FSW)
Metals, 2018 This work studies the metallurgical and microstructural aspects of Friction Stir Welding (FSW) in terms of grain size and microhardness. The modelling is based on the combination of an apropos kinematic framework for the local simulation of FSW processes
