Correlation of STRESS CONCENTRATION with FATIGUE STRENGTH of ENGINE COMPONENTS 450227

RESEARCH work reported in the literature for the purpose of guiding the designer in interpreting his mathematical or experimental stress analysis in terms of fatigue strength is primarily based on tests of simple beam specimens rather than on the actual machine component as manufactured.
Tests of the latter type in which it has been possible to make a direct check on the validity of laboratory stress measurements are reported by the authors, who draw conclusions as to the interpretation of the latter.
The authors say that the results have given them greater confidence in the practical utility of laboratory test methods than would be justified from conventional material strength data.
