Influence of boundary conditions on the response of multilayered plates with cohesive interfaces and delaminations using a homogenized approach

R. Massabò

Stress and displacement fields in multilayered composites with interfacial imperfections, such as imperfect bonding of the layers or delaminations, or where the plies are separated by thin interlayers allowing relative motion, have large…

A consistency assessment of coupled cohesive zone models for mixed-mode debonding problems

R. Dimitri, M. Trullo, G. Zavarise, L. De Lorenzis

Due to their simplicity, cohesive zone models (CZMs) are very attractive to describe mixed-mode failure and debonding processes of materials and interfaces. Although a large number of coupled CZMs have been proposed, and despite the…

Dynamic debonding in layered structures: a coupled ALE-cohesive approach

Marco Francesco Funari, Fabrizio Greco, Paolo Lonetti

A computational formulation able to simulate crack initiation and growth in layered structural systems is proposed. In order to identify the position of the onset interfacial defects and their dynamic debonding mechanisms, a moving mesh…

Numerical modelling of intergranular fracture in polycrystalline materials and grain size effects

M. Paggi, P. Wriggers

In this paper, the phenomenon of intergranular fracture in polycrystalline materials is investigated using a nonlinear fracture mechanics approach. The nonlocal cohesive zone model (CZM) for finite thickness interfaces recently proposed by…

Local zigzag effects and brittle delamination fracture of n-layered beams using a structural theory with three displacement variables

Roberta Massabò, Ilaria Monetto

Equivalent single layer theories for layered beams effectively and accurately predict global displacements and internal force and moment resultants using a limited number of displacement variables. However, they cannot reproduce local…

Composite lay-up configuration effect on double and single sided bonded patch repairs

Toufik Achour, Fayçal Mili

Understanding the failure modes of damaged or cracked structures and repaired by bonding a composite patch is an essential point to improve its resistance to failure and subsequently extend its service life. In the present study, a 3D…
