Gas assisted injection moulding: Experiment and simulation. Industrial machine experimental studies of the effect of process variables on gas bubble formation, and with simulation based upon a pseudo-concentration method.
The gas assisted injection moulding process is an important extension to conventional injection moulding. Gas assist can be applied in a number of ways, but here the penetration of a gas bubble through the polymer melt is of interest. A 3D fi nite element implementation of a pseudo concentration …

The undrained behavior of saturated, dilatant silts
… to investigate whether cavitation and dissolved gases exiting solution from soil pore water are the cause of the erratic undrained behavior often observed in triaxial tests on saturated, dilatant silts. The literature indicates that ground water contains various amounts of dissolved gases and …

Atomistic Simulation Of Plasma Interaction With Plasma Facing Components In Fusion Reactors
… became amorphous prior to deuterium cluster formation, and gas bubbles were observed. The formation of gas bubbles were caused by the near surface deuterium super-saturation region and the subsequent plastic deformation induced by the local high gas pressure.</p> <p>Tungsten irradiated by …

In-line measurement of solibility of physical blowing agents in thermoplastic melts as related to extrusion foaming
… solubility data by observing the onset of gas bubble formation/dissolution. This method offers a number of advantages over the existing conventional methods. It can be easily used to obtain solubility data for many foamable thermoplastic-physical blowing agent systems at high pressure and …

Mechanisms of layer-transfer related to silicon-on-insulator structures
… growth enhanced by the effect of inertial gas bubbles and hydrogen plasma processing. This dissertation also studied suitable wafer bonding methods for a novel method to produce nanoscale silicon-on-insulator materials. Silicon wafers were implanted by different elements (He, N, Ne, Ar) at …
