Crack creation problem - FRANC3D with ABAQUS
I am trying to develop a model in ABAQUS and perform crack analysis using FRANC3D. I am having a problem right at the beginning.
I am able to create the model in ABAQUS and write the .inp file. I open this file in FRANC3D and am trying to insert a curved crack. I repeat a 'curved crack'. The crack is not planar. When I try to define the crack front using 'user defined points', the software is approximating all the points I enter to a best-fit 'plane'. So it is generating a planar crack when i wanta curved crack.
On Mechanistic Approach to Modelling R-Curve Behaviour
As a follow up to my first blog , I would like to know if the experimental data of applied loads and crack sizes or lengths, are sufficient to model the R-curve behaviour via the Fracture Mechanics approach.

Could anyone help on Drucker-Prager model?
I am using exponent Drucker-Prager model at the moment, is there anyone can tell me where the follow exponent D-P eqation comes from originally?
(σ e)(σ e)=λ(σt)(σt)-3(λ-1)σmσt
Where λ= is hydrostatic stress sensitivity parameter and equal to σc/σt, σe is effective stress, σm is hydrostatic stress, σc, σt are stresses under compression and tension, respectively.
I Would like to include failure in my model
I am doing my master thesis on crash simulation of plywood (7 layers-orthotropic material) structures in buses using explicit LS-DYNA FE program. I would like to include failure in my model. Right now I am working on Mat_054_55 (MAT_ENHANCED_COMPOSITE_DAMAGE…..material model from LS-DYNA material library).
Mat_054_55 allows me to get failure by defining anyone of the following parameters,
