Safety and strength coefficients of mechanical structures

Abstract

Mechanical structures have been developed for defining strength coefficients, which confirm the specified reliability requirements and have been referred to as safety coefficients. Safety coefficients have been utilized in the theoretical and experimental development of structures. These coefficients are the products of several particular coefficients found by probabilistic and statistical procedures, namely, the average strength coefficient for meeting the reliability requirements, the relation of the average mechanical tension of the material to the tension guaranteed by GOST, the coefficient for the test plan and the incompleteness of the test results, the coefficient for the difference between the dynamic response coefficients in dummy blocks and mechanical structures, the coefficient for the replacement of multiple loading by single loading, etc. Safety coefficients have been utilized during independent and dependent tests.
