In armchair graphene sheets, crack propagates perpendicular to the applied strain, whereas crack propagation in zigzag sheets occurs at an angle to the straining direction. This occurs due to different bond structure along armchair and zigzag directions as shown in Fig. 1. Videos 1 and 2 show the fracture of armchair and zigzag sheets, respectively.

Hi all,
In engineering sciences, we usually end up using either the second- or the fourth-order differential equations, and the MWR (the method of weighted residuals) works pretty well for them.
The question is: how about the first- and the third-order differential equations? Why don't we see any applications of MWR for these odd-ordered differential equations? What gives?
I am getting displacement and force both zero. I am attaching .cae file please have a look where i am making mistakes.
i want to do crack anlysis in composite.i am thinking to use freefem++ or matlab for this purpose.please suggest me which one should i use.if any other,please recommend.

New research is emerging out of a project where Ohio State University used our software to reconstruct the anatomy of an ant neck. In this project, micro-CT scans of an ant neck were reconstructed using Simpleware software and exported as a mesh for analysis in Abaqus.
