I am trying to simualet Indentation Hardness Testing in ABAQUS and feeling like that there is some problem in my model.

Whenever I try to plot load-displacement curves it gives me bumps in the curve. Any idea, what should I do?

Should I reduce mesh size, I have done but then it gives me error with step size and so on.,

Hi,

I am intrested in Process piping design and saw an institude in India  called IPEBS based in HYDERABAD  that offers such courses. I would like to know if this institude is a good one. Other recomendations are welcome.

Thanks for your information.

Very urgent two enquires:

1. How to model rotational spring element in order to define a curve
like M=k*(theta) where theta is the rotaional angle? It seems that
abaqus could only provide F=kx model.

2. there is a dashpot connector element which behaves like F=C * V
(where C is a constant), can I ask how to model F=C*(dv/dt)=C*a(where a
is the derivative of change of velocity)?

Thanks.

HI

I've been digging on google for some catalogs of aluminiums and steels, to get information about their prices and characteristics. I need to have a perspective of some prices, specially for pipes, for this project I'm working on. 

   The problem is, even with some companies display their products, they won't show their prices unless we make a request and they send a physic catalog. Since I don't have the time to wait for them to send me those catalogs, I'm asking if anyone can send some links, or some pdf's with some information.

Any one help me how to analyse the laminated composite beam using ansys....Is there any ansys tutorial available ?????...

Hi all .. What are the advantages of XFEM over std FEM other than remeshing ? 

Because when ever  XFEM is introduced only remeshing alone is highlighted ... Can the experts from this field please list out the other advantages?

 
All above are in context to Fracture.

thanks in advance.
