Group to support graduate study leading to a PhD in Materials Science
and Engineering at the University of Connecticut starting Spring/Fall 2013.

Dear All, 

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.
