Optimal structural design against elastic instability
In the classical Euler buckling problem, the critical buckling load can be increased by a factor of four if the first mode is suppressed by placing an additional simple support at the mid-point.
The issue of the computation of the deformation gradient in Abaqus
Forums
Hi everybody,
I am trying to model an anisotropic hyperelastic material in plane stress under uniaxial tension
where W=Wiso +Wani= C10*(I1-3)+C4*(I4-1)2 .
When the load is parallel or perpendicular to the fiber direction, the deformation gradient returned by Abaqus matches the theoretical expression obtained after derivation of W.
However, when the fiber direction is neither parallel nor perpendicular to the load, the deformation gradient returned by Abaqus differs
modelling of axisymmetric cold extrusion die by abaqus
my problem is simulation of axisymmetric cold extrusion die. the die is conical, i have to determine die pressure, ram force and temprature in billet as well in die, plz see attached file and see simulation figure, my problem is same as in file,i have facing interaction problem in abaqus while solving this problem. plz help me

My 1st Paper!
Salam and Hi!
My 1st paper was published in Jurnal Mekanikal UTM in June 2008. Please comment and critic on my research works! The paper is here, PREDICTION OF PROGRESSIVE FAILURE IN WOVEN GLASS/EPOXY COMPOSITE LAMINATED PANELS.
Thanks!
How to obtain the exact true stress true strain curve from tensile test
Hi,
The data obtained from tensile test is not reliable after the point of maximum load as neck initiates and triaxial state of stress develops.There is lot of literature in this regard, Can anyone suggest a good method to obtain the exact load disp curve after necking.
regards
