Anotace knihy

Porosity is known to be one of the primary§detrimental factors controlling fatigue life and§total elongation of several cast alloy components.§The two main aims of this work are to examine pore§nucleation and growth effects for predicting gas§microporosity and to study the physics of bifilm§dynamics to gain understanding in the role of bifilms§in producing defects and the mechanisms of defect§creation. §In chapter II, a technique based on the combination§of a set of conservation equations that solves the§transport phenomena during solidification at the§macro-scale and the hydrogen diffusion into the pores§at the micro-scale, was used to quantify the amount§of gas microporosity in A356 alloy castings. The§results were compared with published experimental§data. In the reminder of this work, the Immersed§Element-Free Galerkin method is presented and used to§study the physics of bifilm dynamics. The IEFGM is an§attractive technique for simulating FSI problems§involving highly deformable solids. §The analysis should help shed some light on the§IEFGM, and it should be specially useful to§professionals in engineering interested in§modeling processes involving large deformations.
