contact damping coefficient

Hello,
I'm modelling an impact of a rigid body with a deformable plate (shell elements) in the dynamic explicit analysis. When defining contact parameters, I can add the damping coefficient. I'd like to know what value is typical for this parameter? After some computations, I've found that 0,01...0,05 was rather good for my model. Is that a reasonable value?
Thanks
Congratulations to Professors Jan Achenbach, Zdenek Bazant, Pol Spanos, Zhigang Suo and Wei Yang for receiving the ASME awards
In addition to the ASME awards related to the Applied Mechanics Division, some prestigious society awards will be given to mechanicians at the IMECE, Houston, Texas, in November 2012.
Professor Jan Achenbach of Northwestern University will receive the ASME Medal. [ASME Medal, established in 1920, is the highest award that the Society can bestow and is to recognize “eminently distinguished engineering achievement.” Only one ASME Medal may be awarded annually.]

Hello, I would like to know under what situation will a stiffness matrix in a FEM problem become non-symmetric? Is there any good reference to this topic? Thanks.
How to design vanes in unsymmetrical elbows
Hi everyone,
I want to ask, does anyone know how to design vanes for unsymmetrical elbow? At least can you give me some calculation recommendations to design it? I am doing air simulation inside ductings for my final project. Thanks all
Safety Factor and Material Factor or Amod, what is the difference?

Hello, everyone! When talking about allowable stress, Safety Factor is introduced. While in offshore engineering, there are allowable stress modifier in API and material factor in NPD. So what is the difference between safety factor and allowable stress modifier or material factor? Are they used in special load conditions?
You help will be appreciated. Many thanks!

Awards will be presented at the AMD Banquet, scheduled on Tuesday, 13 November 2012, during the ASME International Mechanical Engineering Congress and Exposition, to be held in Houston, Texas, 9-15 November 2012 at the Hilton Americas and the George R. Brown Convention Center.

residual stress and strain definitions (through-thickness) in ABAQUS/Explicit
Forums

Hello everyone,
I need some help regarding the definition of initial residual stresses and plastic strains in a shell finite element (S4R) model in ABAQUS/Explicit.
I have determined the residual stress distributions and initial plastic strains and I need to assign these distributions to a given element set.
I understand I should be looking at:
