A benchmark study of simulation methods for high-cycle fatigue-driven delamination based on cohesive zone models
TL;DR: In this paper, six different computational methods for simulating fatigue-driven delamination cracks in composite laminated structures under cyclic loading are presented, all of which are based on cohesive zone models and are aimed at high-cycle fatigue simulation.

Application of fracture mechanics to predict the failure load of adhesive joints used to bond CFRP laminates to steel members
TL;DR: In this paper, the fracture properties of the adhesive material and the accuracy of numerical methods using this information, in order to predict the strength of adhesive joints in steel members bonded with carbon fiber reinforced polymer (CFRP) laminates, were evaluated.
Cohesive Elements for Shells
TL;DR: In this paper, a cohesive element for shell analysis is presented, which can be used to simulate the initiation and growth of delaminations between stacked, non-coincident layers of shell elements.

High fidelity simulation of low velocity impact behavior of CFRP laminate
TL;DR: In this paper, a finite element (FE) model which simulates damage extent of CFRP laminate subjected to low velocity face-on impact is proposed The validity of the model is demonstrated by comparing experimental and numerical results for two different CFRPs with different stacking sequence and boundary conditions Experimental damage extent were obtained from the drop-weight test and non-destructive inspections (C-scan, radiograph and X-ray CT) Numerical results obtained from FE analyses done on Abaqus/Explicit 2016

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.

TL;DR: In this paper, the authors used the Weibull-type approach to measure the effect of size effect on structural strength of a crack and its size effect in terms of the number of cracks and the size of the cracks.
