Composite crushing + CZONE application

tsai-wu failure criteria ...

czone

Hello,

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

I am modeling the coupon using S4R elements and the impactor as a discrete rigid shell plate with a slow constant crushing speed or high initial velocity for quasi-static and dynamic crushing simulations respectively.

I am using Hashin damage in Abaqus/Explicit and Hashin and also Tsai-Wu on CZONE application.

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

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.

OBJ files - ABAQUS/CAE

OBJ file

Dear collegues,

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

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

Thank you for your time and attention.

Best regards
