Residual stresses in high pressure die castings

, 2013
This study has compared different methods for measuring residual stresses in high pressure aluminium castings. The hole-drilling and X-ray diffraction method were used. A stress lattice were used. The results from the measurements were then compared with simulations of residual stresses.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Simplified Models for High Pressure Die Casting Simulation

Procedia Engineering, 2015
The simulation of the High Pressure Die Casting (HPDC) process is a complex type of simulation. The industrial procedure is based on consecutive manufacturing cycles that must be taken into account in the simulation. Moreover the part geometries use to be complex and the alloy is injected at really high velocities.

A new approach to enhance the efficiency of local squeezing during high pressure die casting of aluminum alloys

Materials & Design
High Pressure Die Casting (HPDC) produces near-net-shape components with varying wall thicknesses, leading to heterogeneous solidification conditions. These effects led to inhomogeneities, which significantly affect mechanical properties. Local squeezing

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

Advanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.
