Abaqus damage evolution- Fracture Energy Values

Hi all,

I am trying to model an impact event but need to find out: 

  • Long. Tensile Fracture energy
  • Long. Compressive Fracture Energy
  • Transverse  Tensile Fracture Energy
  • Transverse Compressive Fracture Energy

 for a Glass/epoxy UD laminate.

 I tried to use Mode I and Mode II tests results for my model but not sure about it. I assume those Mode I and Mode II values for Transverse Fracture Energies, but no idea about the Longidutinal fracture energy values.

 Does anyone have any ideas about which values should I use or any suggestions from the literature?

Thanks

E.S.

Hi all,

I am also trying to simulate a crushing simulation of a composite open/closed section in ABaqus/Explicit 6.10.

I am also missing the longitudinal and transverse compressive and tensile fracture energies.

Does anyone knows how can I determine these values?

Thank you for your time and attention!

Best regards,

David Melo
