Abaqus Numerical modeling of spinal motion segment
From the review introduced above it is apparent that the mechanism of WPS effects is
still an attractive subject. This paper describes the results of a comprehensive FEM calcula-tion carried out for various regimes of Loading-unloading-cooling-fracturing (LUCF) cycles and a great variety of WPS operations with complex loading and unloading steps different in signs. Analyses are focusing on the roles played separately by the residual compressive stress, macro-blunting of original notch and the prestrain-deactivation of cleavage initiation by micro-blunting of conventional second phase particles in notched specimens.
