WebWe find that characteristics-sparse SDFs formed from a few such factors—e.g., the four- or five-factor models in the recent literature—cannot adequately summarize the cross … WebJan 19, 2024 · The drying creep evolves in time similar to shrinkage and exhibits a similar dependence on cross-sectional thickness D (Fig. 3.3), while the basic creep is independent of D. Figure 3.4 shows the classical tests of Pickett [690], which were the first to demonstrate the drying creep and revealed that it occurs both for drying and wetting.

Webracy for the casting shrinkage. The solid fraction threshold, at which the transition from the fluid dynamics to the solid dynamics occurs, was found to be important in predicting shrinkage factors (SFs). It was found that accurate predictions were obtained for all measured dimensions when the shell mold was considered a deformable material.
