Finite Element Simulation of Dimensional Shrinkage and Residual Stresses in Material Extrusion of a Highly Filled Metal-Polymer Feedstock (17-4PH)

This preprint presents a staged thermo-mechanical finite element model of the printing, cooling, and detachment stages of material extrusion (MEX) for a highly filled 17-4PH stainless-steel feedstock (95.5 wt.% metal loading, paraffin-wax/stearic-acid binder). Extending the seque...

Numerical Simulation of the Bending Behavior of a Topologically Optimized Structure Printed in ABS by FDM: G-Code-Driven Mapping of Local Material Orientations

This preprint presents an original dual-branch numerical pipeline for simulating the bending behavior of an MBB (Messerschmitt-Bölkow-Blohm) beam, topologically optimized using the SIMP method and manufactured in ABS by fused deposition modeling (FDM). Starting from a single G-co...

A hybrid global maximum power point tracking of a PV-Battery system under complex partial shading conditions using horse herd optimization algorithm and a variable step size perturb and observe

Photovoltaic (PV) arrays are sensitive to variable environmental conditions, which requires continuous regulation to maximize power, this makes maximum power point (MPP) trackers an essential element in every PV generation system, in particular, when PV arrays are under nonunifor...

Service-Life Prediction of Core Inserts Under High-Volume Plastic Injection Molding Conditions

High-volume injection molding systems for plastic part production operate under severe thermo-mechanical loading repeated at high production rates. Therefore, premature breakage of hot-work tool steel core inserts directly interrupts production continuity and creates a recurrent...
