Renewable Power And Sunlight Energy - Thin-Film Solar Panel Products

Submitted by gloriatrack on Tue, 12/13/2011 - 21:56

As technology constantly advances there are many new green technologies released each day that can help us improve our energy efficiency. One such technology is the "Thin-Film Solar Panel." How are thin-film solar panels being utilized by consumers today? How do they compare against traditional photovoltaic (PV) panels?

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

surface effect

buckling delamination

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,

Finite element simulation of substrate and film

finite element

Hello Everybody here :

I am going to use ANSYS to do some finite element simulations of interface crack between

substrate and film and the residual stress of substrate and film. I don’t how to define the interface of the substrate and film in finite element model. How to connect the substrate and film? Just glue the substrate and film or use other element to deal with it? Thanks a lot.

Cardboard rolls on the nanoscale

Submitted by Peter Cendula on Wed, 01/12/2011 - 16:08

Everybody knows that cardboard paper can be a highly
anisotropic material. You can easily bend or roll it in one direction
and it is stiff in the other. If you take a close look you will find
that the paper is periodically buckled along one direction. We have now
exploited this phenomenon on the nanoscale to define the roll-up
direction of ultra-thin membranes on a substrate surface.

periodic boundary conditions in ABAQUS 6.9-1

Submitted by perzo on Thu, 10/21/2010 - 11:57

Hi

I have a problem with applying periodic boundary condition. I have used *EQUATION in constraints for opposite nodes and surfaces. But I still have some problem with that for sure I making some simple mistake. If anyone could look at my model and find problem. Abaqus version 6.9-1 .

Thanks a lot.

Hi,

For a personal project I'd like to find a free program that lets me see what happens when I take a beach ball and apply greater and greater weight on it. I'm specifically interested in the deformation of the ball, and the stresses in the material.
