abacus modelling

Hello there, I need your help if you can please email me as i can not log into imechanica all the time to check my blogs because the website jams most of the time ,i will appreciate your help.

I need to draw a normal rectangle using abacus and then mesh it and apply force on it and to be as beam???

i tried to do it but i keep getting an error message saying 4 elements have missing property definitions???

If any one can help this is My email is nl1422 [at] hotmail.com

wave propagation Hamilton Systems

I am a junior graduate student now, and very interesting in wave motion. My advisor Prof. Zhong wanxie and his PHD student qiang Gao have developed a precise numerical technique to solve the Rayleigh wave frequency equation, which can avoid the missing root. They did a systematic work involving surface wave propagation in a transversely isotropic stratified solid resting on an elastic semi-infinte space, wave propagation in the anisotropic layered media and the propagation of stationary and non-stationary random waves in a viscoelastic, transversely isotropic and stratified half space.

Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates

thin metal films

We study the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer-supported metal films agrees well with the simulation results.
