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

Numerical Stability of Lanczos Methods [PDF]
, 1999 The Lanczos algorithm for matrix tridiagonalisation suffers from strong numerical instability in finite precision arithmetic when applied to evaluate matrix eigenvalues. The mechanism by which this instability arises is well documented in the literature.
