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.

Please recommend a good undergraduate textbook for 'mechanical vibrations'...

Thanks in advance.

what a hypocritical website this is.... almost 200 reads and not one comment. high academic qualifications of most members seems to be creating an elastic sheath of EGO!

Thanks for reading this too. :)

Dear All,

 I have seen it being mentioned that the material at an updated configuration in an Updated Lagrangian Formulation (say in FEM) may not remain isotropic, even if the reference configuration was isotropic.  However, I have not seen any detailed discussion on the matter.

Hence, I would request your comments on:

hi

i am interesting to be known with new approch in simulation of process or nano technology .

please help me.

thanks

Hi all,

I have attached a single slide ppt file with this blog. In this slide, there is a hollow cylinder subjected to internal pressure and non-uniform axial load. All the translations at the bottom of the cylinder are fixed. As a whole the cylinder is subjected to a complex loading. The cylinder is modeled using SHELL elements in ANSYS. Now I know how to carry out non-linear buckling analysis in ANSYS.

what happens when the body is subjected to hydrostatic forces and why it is considered that a body doesnot yeild under hydrostatic stress
