Structural integrity (STIN): Local approach methods in siulating material failure

Research output: Chapter in Book/Report/Conference proceedingChapter or book articleProfessional

Abstract

Local approach methods have evolved from damage mechanics models to means of providing quantified estimates of material failure behavior under various rupture mechanisms. High emphasis has been given to cleavage initiation, usually considered to induce the most profound risks to structural integrity. Overall, research has lately focused on comprehending the micromechanical background of ductile and brittle failure models and evaluation of their performance. The results have demonstrated that the promise of material parameter and failure evaluation transferability can be met, even though developments within the material models themselves are required. Current paper presents the latest results attained with respect to fracture behavior in the ductile to brittle transition and upper shelf temperature regions.
