Chiral topographic instability in shrinking spheres

Submitted by Fan Xu on

Many biological structures exhibit intriguing morphological patterns adapted to environmental cues, which contribute to their important biological functions and also inspire material designs. Here, we report a chiral wrinkling topography in shrinking core–shell spheres, as observed in excessively dehydrated passion fruit and experimentally demonstrated in silicon core–shells under air extraction. Upon shrinkage deformation, the surface initially buckles into a buckyball pattern (periodic hexagons and pentagons) and then transforms into a chiral mode.

implementing carbonfiber properties in 2D

Submitted by Sarah A. Eassa on

Hi all

I was wondering about implementing carbonfiber properties (engineering constants) in 2D in abaqus.
This error keeps popping up "The third axis should be in the hoop direction".

I am adjusting material orientation so that the primary axis X sould be out of the paper. But in 2D the Z axis must be out of the paper.

Is there any solution to that?

Thanks

Solution of plane strain problems based on a new model

Submitted by Jiang Ke on

For orthotropic plane strain problems, the various existing calculation methods are very complex. The orthotropic plane strain problem with cracks have solved by using a new element model, and compared with the finite element method, it can be found that the displacements and the stresses of the two methods are in good agreement.
