Hi,

I am trying to simulate wave propagation in ANSYS for the following model,

Model size = 1e-6 m x 1e-6 m

I am using plane 182 elements with plane strain option. The material properties are E = 74 GPa, Poisson's ratio = 0.1 and density = 2530 kg/m3.

I feel that, even though health and safety regulations are
continually becoming more and more advanced, and the legislation develops after
most major incidents, a major factor aiding incidents occurring is the involvement
of humans. I understand that this sounds blatantly obvious (I mean, If humans
weren’t involved, there wouldn’t be any equipment etc. to cause a risk), but I’m
talking more about the risk due to the lack of common sense, or, more bluntly,
human stupidity. Whilst working for an valve maintenance firm,  I once saw a >3m long actuator suspended
from a crane around 2m off the ground with a valve technician standing on top
of it, adjusting part of the lifting mechanism it was suspended from.

It
should be banned. NO to Fracking

During
a visit to Ales a region in southern France, The former President of France
Nicolas Sarkozy maintained the ban on fracking of shale gas until a better
technology that will not harm the ecosystem and destroy the landscape
(Bloomberg BusinessWeek).

The
process of fracking (extraction) and one of the major components of Shale Gas
are both hazardous, thus my outright kick against it. An in-depth look at the
two key drivers to my conclusion;
