精选优质文档-倾情为你奉上Effect of Porosity on Deformation, Damage,and Fracture of Cast SteelR.A. HARDIN and C. BECKERMANNA combined experimental and computational study is performed to investigate the eect ofcenterline shrinkage porosity on deformation, damage, and fracture of cast steel under tensiletesting. Steel plates containing shrinkage porosity are cast in sand molds, machined into testcoupons, and tensile tested to fracture. The average volumetric porosity in the gage section of
