A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-up to tubes with defined number of rotations. The wrinkles are also rather common in macro- and microscale thin films.
Here, we developed an equilibrium phase diagram for the shape of
compressively strained free-hanging films by total strain energy
minimization.

Hi all,

If you can pls advise me to modelthis experiment.

First I have applied a constantload for the steel member.

Then I have increased thetemperature of one of the member surface with time

until the member got failed.

This resulted in non-uniformtemperature variation across the section.

I have measured the temperaturesof the different surfaces of the member and

I would like to use thesetemperature values in my structural modelling.

Now I would like to model themember so that I can find out the time

What are the effects of magnetism on stresses while material is under loading condition?Is there any relationship between magnetism and stress?

Thanks!
