Napěťová analýza odstředivě litých ocelí

Abstract

The present thesis studies the emergence of tension states in the steel castings. The study of post-casting tension used two types of sample castings of a cage body. The tension level was derived from the measured value of linear and relative shrinkage, and from the size of cracks and ruptures in the sample castings. In addition, a microstructure and mechanic properties of the sample castings were evaluated. The results of actual measurements were compared with the computer-made simulation of solidification and strain in the tested geometry of test specimen.
