Post Buckling of Thin Shells
It is difficult to conduct post buckling analysis of thin shell under axial compression using Arc Length method in Ansys.
The Minimum & Maximum Arc Length radii are chosen by hit & trial.When imperfections are incorporated in the FE model, some times the solution diverges at a higher critical load that the eigen value buckling, which should be vice versa in actual. Some times , negative eigen values are also shown.
Is there any easy way to solve this nonlinear stability problem?

What is the meaning of nonhardening Material
I am getting confused with a definition of nonhardened Material as I read the book Fracture Mechanics written by T.L. Anderson.
I got two understandings and am not sure which one is right.
1) Material with lower yield strenth, which was not work-hardened.
2) d(stress)/d(strain) = 0 after yielding.

STRESS DISTRIBUTION IN NANOTUBES
Nice and low-cost introductory texts
There are two very nice companion texts on continuum mechanics and nonlinear elasticity printed by Dover recently: "Continuum mechanics" by Spencer and "An introduction to the theory of elasticity" by Atkin and Fox. Great and fairly affordable reading!
Runing of input file
Dear friends,
if i have one input file i will import by file---model---inputfile
the i will see what they did in othermodules, for learning from exapmle problem
but if i have morethan one input file mean main input file and node information and element information both are seaprate input for reduc thesize of file.
how to import via part--model--
so how to merge this more than one input file
thanks and regards

Neuber Plasticity correction
All,
Can we used Neuber Plasticity correction method to composite material to estimate equivalent elasto-plastic stress from linear elastic stress results ?
Can anybody provide some document which support the usability of Neuber method to composite ?
Thanks

Notes On Linear Static Analysis & Dynamic Analysis
Hi friends i am new user and 1 year experienced guy in CAE field in Pune, India.
i wants some tips/notes in Linear Static Analysis & non Linear analysis.
Tips/ Notes about softwares like MSc nastran, Abaqus will be useful for me. So plz tell me how can i obtain them.
elastomer gasket life prediction
my project is life prediction of elastomer gaskets in ic engines using fea. how can i select the constitutive model and the life prediction associated with which mechanism whther stress relaxation, stress softening or excessive creep
