Hi all,

I'm a PhD student with Electronics Engineering background. I'm doing a research in microcantilever based biosensors.

I'm having difficulties in understanding the adsorption-induced stress in microcantilever.

I would appreciate any advice or pointers on what materials that I can refer to. Besides that, what is the software that I can use to simulate this adsorption phenomenon? 

Thanks in advance.

Cheers,

Yang

Hi All,

The new Abaqus 6.9 release offers new capabilities for fracture and failure (XFEM) and much more.   http://www.simulia.com/products/abaqus_fea

I am trying to perform postbuckling analysis of plates in ANSYS. But something confuses my mind. After linear buckling analysis I use scaled firtst buckling mode shape to generate initial imperfections. Then I initiate nonlinear geometric analysis by NLGEOM command. Collapse load or final converged iteration changes according to NSUBST option. I am trying to give higher Substep to obtain more sensitive and reliable results like 10000. But NSUBST with 100 sometimes reaches higher loads than using 10000. Which one is a correct approach?

Could anyone help me?

The residual stress in a metal do not depend on its hardness, but from the module of elasticity or Young module and from its chemical composition (density).

Hi. I'm now starting my PhD on a project on sintering of hard metal.

I'm doing a literature study, but I have failed to find any articles that uses FE analysis on the micro/mesoscale. All of them seems to handle this only with a homogenized model on the macroscale.
If I get to be picky, I would prefer something with hardmetal, but at this point, anything would be great.
I would also be very happy to find any suitable reading on FE-analysis on solid-liquid-pore mixtures.
