摘要：

This paper describes the possibility of using analytical and numerical models of a void-type casting defect to determine the growth of local stress in the defect environment during static and time-varying mode of loading. The value of this stress may be one of the factors deciding about the admission of casting to operation. The analysis of the proposed models was conducted on the example of a pressure valve made from the cast iron of EN GJS 400-15 grade.
