Numerical Simulation of Abrasive Water Jet Cutting Chemical Pipeline Based on SPH Coupled FEM

Chemical Engineering Transactions, 2016
Abrasive water jet (AWJ) is an advanced machining technology, which presents better cutting quality than traditional machining methods. Because the large deformation in finite element method (FEM) tends to produce mesh distortion, this paper enables ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A Smooth Partition of Unity Finite Element Method for Vortex Particle Regularization [PDF]

SIAM Journal on Scientific Computing, 2017
We present a new class of $C^\infty$-smooth finite element spaces on Cartesian grids, based on a partition of unity approach. We use these spaces to construct smooth approximations of particle fields, i.e., finite sums of weighted Dirac deltas. In order to use the spaces on general domains, we propose a fictitious domain formulation, together with a ...
