Composite crushing + CZONE application

Hello,


I am modelling a crushing simulation of a composite corrugated coupon using Abaqus/Explicit and CZONE Abaqus' application.

Debonding simulation - XFEM fracture criterion - delamination

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

- XFEM-based LEFM (using VCCT) fracture criterion.

DCB test - CONTINUUM SHELL ELEMENTS vs SOLID 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.

OBJ files - ABAQUS/CAE

<strong><p>Dear collegues,</p>

<p>I will maybe receive an OBJ file used to  simulate the Hashin 3D failure criterion in a composite tube crushing simulation.</p>

<p>Do I need to install the FORTRAN compiler on my computer to run this OBJ file with my Abaqus/CAE simulation?</p>

<p>Thank you for your time and attention.</p>

<p>Best regards</p>
