A multi-scale modeling framework for instabilities of film/substrate systems

Spatial pattern formation in stiff thin films on soft substrates is investigated from a multi-scale point of view based on a technique of slowly varying Fourier coefficients. A general macroscopic modeling framework is developed and then a simplified macroscopic model is derived. The model incorporates Asymptotic Numerical Method (ANM) as a robust path-following technique to trace the post-buckling evolution path and to predict secondary bifurcations.

Postbuckling analysis and its application to stretchable electronics

Dear all,

I would like to recommand a paper on "Postbuckling analysis and its application to stretchable electronics"。 Please find enclosed paper which is published on Journal of the Mechanics and Physics of Solids Vol. 60 (2012) 487–508.

Post-doctoral position at Univ. Pittsburgh: soft tissue buckling

A post-doctoral position is available in the lab of Sachin Velankar at the University of Pittsburgh to conduct experimental research on buckling of soft tissues in cephalopods (octopus or cuttlefish).

I am trying to perform postbuckling analysis of plates in ANSYS. But something confuses my mind. After linear buckling analysis I use scaled firtst buckling mode shape to generate initial imperfections. Then I initiate nonlinear geometric analysis by NLGEOM command. Collapse load or final converged iteration changes according to NSUBST option. I am trying to give higher Substep to obtain more sensitive and reliable results like 10000. But NSUBST with 100 sometimes reaches higher loads than using 10000. Which one is a correct approach?

Could anyone help me?
