## Mathematically exploring wrinkle evolution

Wrinkling is one of the most important mechanical deformation modes (for example, buckling and crumpling) that are omnipresent in our daily life: for instance, wrinkled fingers after soaking in water for a prolonged time, the folds within the brain, and metal wrinkles after a car collision, to name a few.

## Is there any optimal way for a membrane conformal with a given surface

Good day, all!

Currently, I'm interested in the conformability of a membrane with a given surface.

## How to analysis Fatigue of shaft using Ansys or Ncode designlife?

I use ANSYS APDL with code for my shaft with two coating layers(interlayer and coating layer). I already analysis stress of shaft with Ansys. the result is ok and i exported to .RST file. But , when i input my shaft to Ncode, I can't find the interlayer and coating layers.I think this shaft have 3 part(subtrate, interlayer, coating layer)
!substrate materials

Young's modulus (Mpa): 2.1e5
Poisson's ratios:0.3
Density(ton/mm3):8.03e-9

## Conformability of a Thin Elastic Membrane Laminated on a Rigid Substrate With Corrugated Surface

When laminating a thin elastic membrane on a substrate with surface roughness, three scenarios can happen: 1) fully conformed, i.e., the membrane completely follows the surface morphology of the substrate without any interfacial gap; 2) partially conformed; and 3) nonconformed, i.e., the membrane remains flat if gravity is not concerned.

## Symposium in IMECE 2014, Montreal, Canada

Dear Colleagues,

We would like to invite you to participate in a symposium on “Modeling and experimental characterization for the behavior of the micro/nanostructured thin films” in ASME 2014 International Mechanical Engineering Congress and Exposition in Montreal, Canada ( http://www.asmeconferences.org/congress2014/).
