Mathematical method for the assessment of the metal test efficiency and optimization of the pressure vessels and pipes periodic tests

A mathematical approach for the assessment of the metal test efficiency and optimization of the pressure vessels and pipes periodic tests in the case of the absence of accurate information is described. The procedure is of successive corrections of the initial flaw and strength characteristics on the base of metal test results. The Bayes approach is used. It is intended for analysis of the efficiency and optimization of material controls for use in potential hazardous production where high reliability is demanded. This approach used the computer code OPTIM.
