METHOD FOR DETERMINATION OF LIMIT DAMAGEABILITY OF MATERIAL

摘要

A method for determination of limit damageability of material includes sampling two same samples of material, determination after destruction of sample of limit damageability of material. The samples at testing are placed in holders in sequence with carrying out tests on strength either at static, or cyclic load with axial force till destruction of one of the samples. After destruction of one sample one performs measurement of hardness in working zone of not destructed and destructed samples, and by values of hardness one determines limit damageability of material by the method of LM-hardness.
