One of the major objectives of solidification modeling is to determine, prior to pouring, whether porosity, such as massive cavities and dispersed pores, are likely to appear in the casting. The numerical solutions of solidification heat transfer alo

This study is intended to explore a simple and inexpensive method that is able to model the variation and distribution of the heat transfer coefficient at the casting/mould interface. It has been a...

An attempt is made to rationalize the fracture behavior of pearlitic gray irons on both the microstructural and macrostructural levels. Along with the effects of inoculation, those of as-cast section size and carbon equivalent may be rationalized on

The present work is introduced and is shown to be a logical extension of work by Chung and Swift, Ray and Berry, et al. The authors introduce the deep drawing process and analyze the stresses due to radial drawing (including friction), bending the sh
