Abstract: Abstract Employing NSGA-II, this paper aims to achieve a damage tolerant structure enjoying maximum delamination resistance and thinness; therefore, we simultaneously define minimization of laminate thickness and delamination growth as objective functions.

DOI: 10.1016/j.compstruct.2016.11.006
Abstract: Abstract Interfaces adjacent to a 90° ply in laminated composites show a typical zigzag path during the mode I delamination propagation process, which is considered to be closely related to high propagation values of fracture… read more here.

DOI: 10.1016/j.compstruct.2020.113175
Abstract: Abstract This paper discusses two approaches that have been proposed to account for the data scatter observed in delamination growth tests under cyclic-fatigue loading and thereby enable an estimate of a worst-case delamination growth curve… read more here.

DOI: 10.1177/00219983221082039
Abstract: A modeling approach is proposed to simulate delamination propagation in composite laminates under both quasi-static and fatigue loading regimes. Delamination growth is simulated using the Virtual Crack Closure Technique combined with a progressive nodal release… read more here.
