Learning temperature, pressure, and chemical potential
I have updated sections of my notes on thermodynamics. A few thoughts on learning are collected here. Of our world the following facts are known:

Dear all
I'm doing an analysis where i need to evaluate the contact area acoording to hertz theory.
I have a book which shows me every step, except for how to calculate two coefficients, and insteads gives me a table of calculated values.
For the contact patch dimensions a and b, i get the expression
where i need to determine m and n. My book (A swedish book without ISBN) simply states that m and n are functions of theta,
and writes a large table with m and n for different angles

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!
