Fatigue life analysis of un-repaired and repaired metallic substrate using FRANC2D
(2018)
Conference lecture
Restricted access - publisher's policyWe present numerical investigations on fatigue life analysis of un-re-paired and repaired metallic substrate. Most of the engineering structures fail due to fatigue under dynamic loading. While research is mostly focused ... -
Guide for recommended practices to perform crack tip opening displacement tests in high strength low alloy steels
(2016-09)
Article
Open AccessFracture mechanics approach is important for all mechanical and civil projects that might involve cracks in metallic materials, and especially for those using welding as a structural joining process. This methodology can ... -
