..., had completely dissolved in that region; shrinkage cavities and dendrite rich regions were clearly visible. Next to this region, a heat affected zone was present where the grain boundaries had partially melted and precipitates partially disappeared. Considerably high temperatures, in the order of 520...

...Rahul R. Panchal; David O. Kazmer Dimensional consistency is a critical attribute for injection molded part quality and is highly dependent on the polymer morphology, the thermal expansion, and various processing parameters. The dimensional shrinkage can be estimated by knowing the pressure-volume...

... a model to improve the understanding of how leaking occurs and of the mechanisms underlying such as shrinkage and warpage behaviors related to material, process, and design. It shall also be the basis for investigations on the phenomena and development of strategies to improve the systems produced...

...Huamin Zhou; GuoDong Xi; Dequn Li The accurate prediction of residual stresses and shrinkage of the formed picture tube panel is important to achieve high quality and precision of the final product. In this paper, the numerical simulation of shrinkage of molded panels was carried out...

... at pre-defined critical locations. The aluminum alloy extruded beam structure is simplified by a 2-D beam element model. Our methodology consists of applying pre-estimated angular shrinkages for each welding step thus eliminating use of a complex nonlinear transient analysis which would require...
