The surface effect on the strain energy release rate of buckling delamination in thin film–substrate systems

Submitted by tongqing.lu on

Gurtin–Murdoch continuum surface elasticity model is employed to study the buckling

delamination of ultra thin film–substrate system. The effects of surface deformation and

residual stress on the large deflection of ultra thin film are considered in analysis. A

concept of effective bending rigidity (EBR) for ultra thin plate is proposed on the basis of

Gurtin–Murdoch continuum theory and the principle of minimum potential energy. The

governing equations with EBR are formally consistent with the classical plate theory,

How to analyze a short arc using elastic mechanics?

Submitted by Yan Zhang on

Hello, everyone, I am a freshman here, and I am very happy to find this place as a mechanics student. Hope to communicate with everyone here. 

I am studying a hole effected by surface effect. I want to know how to analyze the stress on a short arc.

If you know about it, and you are willing to share it with me, I will be very grateful about it!
