Entropic rigidity of a crumpling network in a randomly folded thin sheet
We have studied experimentally and theoretically the response of randomly folded hyperelastic and elastoplastic sheets on the uniaxial compression loading and the statistical properties of crumpling networks. The results of these studies reveal that the mechanical behavior of randomly folded sheets in the one-dimensional stress state is governed by the shape dependence of the crumpling network entropy.

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.
