A finite element ductile failure simulation method using stress-modified fracture strain model
TL;DR: In this article, the authors proposed a new method to simulate ductile failure using finite element analysis based on the stress-modified fracture strain model, which is used for structural integrity assessment.
Journal ArticleDOI
Damage modelling of adhesively bonded joints
TL;DR: In this article, a cohesive zone model (CZM) was used in conjunction with both elastic and elasto-plastic continuum behaviour to predict the response of a mixed mode flexure and three different lap shear joints, all manufactured with the same adhesive.

Ductile tearing in thin aluminum panels: experiments and analyses using large-displacement, 3-D surface cohesive elements
TL;DR: In this article, a large-displacement formulation for a 3D, interface-cohesive finite element model and its application to predict ductile tearing in thin aluminum panels is described.
Journal ArticleDOI
Predicting the residual strength for environmentally degraded adhesive lap joints
TL;DR: In this paper, a cohesive zone model was used to predict the residual strength of degraded adhesively bonded lap joints, and a mixed mode interfacial rupture element was proposed with a traction-separation law.

A Continuum Model for Void Nucleation by Inclusion Debonding
TL;DR: In this paper, a boundary value problem simulating a periodic array of rigid spherical inclusions in an isotropically hardening elastic-viscoplastic matrix is analyzed and the effect of the triaxiality of the imposed stress state on nucleation is studied and the numerical results are related to the description of void nucleation within a phenomenological constitutive framework.

The relation between crack growth resistance and fracture process parameters in elastic-plastic solids
TL;DR: In this article, an elastic-plastic solid with an idealized traction separation law specified on the crack plane to characterize the fracture process is computed for small-scale yielding as dependent on the parameters characterizing the elasticplastic properties of the solid and its fracture process.
Book
Advanced Fracture Mechanics
TL;DR: This book goes beyond the well developed area of linear elastic fracture mechanics to consider the dynamic and elastic-plastic regimes, and in doing so, extends the subject into a broader range of realistic engineering applications.
