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)

Mechanical Self-Assembly of a Strain-Engineered Flexible Layer: Wrinkling, Rolling, and Twisting

Submitted by zichen on

Self-shaping of curved structures, especially those involving flexible thin layers, is attracting increasing attention because of their broad potential applications in, e.g., nanoelectromechanical andmicroelectromechanical systems, sensors, artificial skins, stretchable electronics, robotics, and drug delivery.

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

Submitted by Shutao Qiao on

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.

Probing the intermediate states between rolling-up and wrinkling thin films

Submitted by Peter Cendula on

Self-positioned nanomembranes such as rolled-up tubes and wrinkled thin films have been potential systems for a variety of applications and basic studies on elastic properties of nanometer-thick systems. Although there is a clear driving force towards elastic energy minimization in each system, the exploration of intermediate states where specific characteristics could be chosen by a slight modification of a processing parameter had not been experimentally realized.
