 1) anaylitical model:

Vertical Cylindrical beam under axial compression load

Height: 26.5mm, Radius: 1.25mm, E: 200000, Load factor k: 2,
Pcritical: 1,347N, Displacement: 0.0364mm 

 2) Beam188 model worked fine with results similar to
analytical one. (txt file attached)

3) Solid186 mold under predicts by a factor of 4 (txt file
attached)

why does the solid 186 element give different results?

Thanks

In this movie taken at 1 Mfps using our new Kirana camera (courtesy Y. Rotbaum), one can see a dynamic tension test of a grroved specimen in a tensile Hopkinson bar. The groove is relatively sharp and 10% of the diameter in depth.

It so happens that the dynamic neck inception occurs outside the notch area, in other words a strong geometrical flaw does not dictate the failure locus. We have performed over a hundred of such experiments. This is a very interesting and challenging observation.... 

 Hello everyone,

 I want to  simulate contact problem by using UEL.I define the surface in the inp file.But abaqus don not 

recognize it. How can I solve this problem?

PS.  Sorry for my English.I hope it is clever enough to understand the problem.

Regards.

How to define JOULE HEAT FRACTION in ABAQUS as a function of temperature? Thank you!

Hello,

Is there some one who obtained the files of this article 'Toward realization of computaitonal homogenization in practice'. Can you share them? Thank you.

Or is there some one who has the experience on the multiscale homogenization of inelasticity in abaqus.?'

Dear all

I want to model 300000 cycles of loading with maximum and minimum value for force as a fatigue loading.I want to model this problem in abaqus and I have several idea for it but not sure about them.would you help me what to do?

many thanks
