delamination

We have an open position as a PhD student in the area of fracture mechanics of fibre composites. The focus of the position is to develop element test specimens, i.e., test specimens that are purposely-designed with the aim of checking the accuracy of model predictions of damage evolution (two or more damage types) in composite structures subjected to static and cyclic loading

Debonding simulation - XFEM fracture criterion - delamination

XFEM fracture criterion

DCB test

direction

Hello

I am using Abaqus/CAE 6.10 to simulate a Debonding test (cohesive behavior for composite delamination).

I ran a Abaqus debonding simulation example (from Abaqus online documentation - Abaqus Benchmark Manual - 2.7.1 Delamination analysis of laminated composites).

The Abaqus/Explicit three-dimensional model with surface-based traction-separation behavior used a surface contact interaction property with:

- default Cohesive behavior

DCB test - CONTINUUM SHELL ELEMENTS vs SOLID ELEMENTS

Submitted by davidrbmelo on Sat, 12/28/2013 - 13:22

continuum shell elements

Hello,

I modelled a 3-D DCB (Double Cantilever Beam) test specimen to simulate crack propagation (delamination) in composite materials.

To do so, I used surface cohesive properties between plates in Abaqus/Explicit, and applied a displacement at the plates tips.

When I used continuum shell elements the crack propagated as expected and the delamination occurred.

Cohesive Analysis with Abaqus/Explicit

Abaqus/Explicit

Hello all,

I'm trying to model composite delamination under non-severe impact on layered composites in ABAQUS/Explicit.

To begin with, I've modeled a 2D aluminum with a finite very low thickness cohesive layer with traction-separation behavior between. Then, I give some displacement to the middle-top node to simulate an impact scenario. However, even in this simple configuration, I'm having stress distribution problems when the models with cohesive layer between and without cohesive layer are compared.

How to plot Fracture toughness vs Crack length in Abaqus for Delamination problem

Submitted by charls2vimal on Wed, 04/17/2013 - 04:57

software

crack

finite element analysis

I've modelled a DCB specimen and applied Boundary conditions and load... I followed the same procedures given in abaqus documentation... As expected the crack initiates and propagates along the interface... I can get the Resultant force vs displacement plot from the analysis.. But i dont know how to plot the fracture toughness vs crack length plot in ABAQUS..

Please help me... Your suggestion would really help me a lot..
