Assessment of steel mechanical characteristics of non-standard compact specimens under statistical tests

Abstract

It is necessary to evaluate possible changes of mechanical characteristics while determining reasons of equipment destruction as a result of implementation of emergency situation. Limited amount of the material collected at the local fracture point requires the use of compact testing specimens. Practical implementation of the method requires establishment of dependence setting correlation between characteristics which were determined under the standard method and the method that uses compacts specimens. In the present research as exemplified by the steel 20 for recalculation of values of yield limit determined by different methods.
