STRESS MODELS AND THEIR APPLICATION IN EXPLANATION OF CASTING DEFECT INFLUENCE ON THE CAST PART MECHANICAL BEHAVIOURAbstract
The article examines possible use of analytical and numerical models of casting defects of a void type in determination of local increase of stresses in the vicinity of casting defect. The stress level can be one of the factors that will decide about the casting acceptance for service. The proposed models were examined on the example of a pressure valve made from cast iron of EN GJS 400 - 15 grade.
