Hi, I wish to plot tangential stress in nodes around a circle. How to accomoplish in ABAQUS? Thanking you.

I am trying to make a material model for my FEM come and while deriving Elasticity tensor I found a term where I have to do some tensor operation. It is as below

P:C:P^T  where all the terms are 4th order tensors. Now I konw the result of this should be a 4th order tensor only as this term is in addition with other 4th order terms. Here any (A:B) indicates Double dot product between A and B. 

Please help me out with this if you know or suggest some good tensor calculus book where I can refer for my problem.

Thanks.

This is a basic question regard to elsticity fem.

How to compute traction boundary integration numerically in elasticity fem under general situation? That is:

\int_{\Gamma} [N][t] d\Gamma,   here [N] is shape function and [t] is surface traction

Thanks a lot

Saint-Venant’s Principle in elasticity  has its over 100 year’s history. Boussinesq  and Love  announced general statements of Saint-Venant’s Principe. The early authors made  important contribution to the principle. Zanaboni “proved” a theorem ，trying to concern Saint-Venant’s Principle, but in the present paper we will prove that Zanaboni’s theorem is false.

Hi everybody

 I want to ask you regarding the general pattern of diagram da/dn Vs. DeltaK(stress intensity factor) for Variable amplitude loading? Could we share our knowleadge in this case?

Regards,

Pls i am new to Ansys just learning how to use it for my research project on composite brake disc. pls can someone help with the following;

1. procedure for thermo-mechanical analysis

2. setting boundary conditions

3. meshing application

i will be very glad if i can get this informations it will really go along way in assisting me for my reseach work. debisi1 [at] yahoo.com (debisi1[at]yahoo[dot]com)

 thank youvery much
