Abaqus CAE- buckling analysis eigenvalue
Dear members,
my question is about how to use the Abaqus CAE eigenvalue for a linear buckling analysis.
I did a linear buckling analysis for a gFRP vertical panel (h:270 thick:20 w:50 cm). I applied a uniform pressure with value 1 on the top of the panel along the Z axis.
Mode 1 gives me an Eigenvalue of 52853 (please see the attachment). I know that in order to obtain the maximum buckling stress I should multiplicate the eigenvalue for the load appied. It means that the value for the buckling stress is 52853 (N/cm2).
Example problems for tire modeling in Abaqus or Pro Engineering
HI,
I am just a begineer in modeling and FEA analysis of tires. Can anyone please provide me with the tutorial or anything for modleing of tires in Pro Engineering or Abaqus and FEA techniques for tire analysis. I would be very glad to have any kind of help. Looking forward for the help. thank you.
Best Regards,

Slow-Fast Crack Propagation in Ferroelectric Single Crystals
Dear Colleague,
I have uploaded a video which shows the simulation of Slow-Fast crack propagation in ferroelectric single crystals:

Looking for a postdoc position (Thermoelectric material)
I am an engineering doctor of School of Physics in Shandong University, China, graduated in July of 2011. And I have, during the doctor's research period, actively engaged myself in the area of thermoelectric material for 5 years, focusing particularly on the oxide thermoelectric material and module. I keenly desire to obtain a post-doc. Research position in a thermoelectric research group, and further continue the study of thermoelectric.Most of my work has published in peer-viewed journals. So I can do academic writing by myself.
Indentation simulation, Contact problem, ABAQUS CAE specialists , please help
Dear All,
I have the following problem. I simulate an indentation in two steps. At first step the indenter penetrate to the material. At the second step it withdraws from it. The problem, at the second step force simply drops. What could be the reason? Incorrect boundary conditions, very soft behaviour of material??? Specialists, please help.
Best regards

How to Combine Shell Element and Solid Element in ANSYS
Hello Everybody
I'm currently working on on the tubular weld of joint modeling using ANSYS
Problems that I faced was how to combine elements of the shell (for chord and brace) with solid elements (for weld) so that stress transfer can occur between two elements
one technique that I know is using MPC
is there any among you who has a tutorial about it ..?
please help.....
Stribeck Curve Analysis Using Tribometer
When lubrication is applied to reduce the wear/friction of moving surfaces an increasing load can shift the lubrication from several regimes such as Boundary, Mixed and Hydrodynamic Lubrication. The fluid viscosity, the load that is carried by the two surfaces and the speed that the two surfaces move relative to each other combine to determine the thickness of the fluid film. It is this process that determines the lubrication regime. How the regimes react to friction is shown in what is called a Stribeck curve.
