DOI: 10.1016/j.marstruc.2020.102787
Abstract: Abstract This study explores the use of localized necking for failure modeling in maritime crash analysis, using large shell elements. The assumption that the failure of a large shell element occurs simultaneously with the onset… read more here.

DOI: 10.3390/app11093774
Abstract: The ductile fracture of thin-shell structures was studied here using a localized necking model. The punching experiments for unstiffened and stiffened panels were compared with numerical predictions using a combined ductile fracture and localized necking… read more here.
