Abstract

This paper establishes the possibility of using an integrated approach based on computer simulation and coercimetric control for assessing the fatigue life of 40X steel samples in the initial state and after surface plastic deformation. It is shown that the characteristic feature of the combined use of magnetic control over the coercive force and computer simulation is the possibility of detecting the initial stages of defect origination and preventing their development to critical sizes.

 

Keywords: computer modeling, coercive force, state of the surface, fatigue life
