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
Hi friends,
I need to transfer stiffness and mass matrices from ABAQUS to Matlab. ABAQUS does generate matrices but those can be re-used by ABAQUS only. Is there a way to use these matrices in matlab. I know about SDT toolbox for matlab and I-MAT but they are costly.

Hi Everyone,
I have to confess here that I do not have a mechanics background but I am currently working on a problem where i have to solve the Navier equation with non-uniform Lame constants of an object. If anyonme could guide me towards the necessary literature or any other resource it would be very helpful. Sorry for any inconvenience.

Hello All
I am trying to read the text book Tensor analysis by IS Sokolnikoff and stuck in
chaper 1, there is some confusion in my mind regarding orthogonal transformations,
change of basis and and a transformation representing deformation of space.
Please bear with me if my confusions are unfounded.
1) Is is safe to say that transformation representing deformation of space acts on
vectors where as transformations representing the change of basis acts on
components?. (if yes then the following questions are resolved and need not be
looked)
2) Sokolnikoff builds up the reasoning for orthogonal transformations based on
deformation of space (i.e orthogonal transofrmations keep the length of vector
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!
Salam and Hi!
Can anyone share how to determine/convert from Volt Data to Strain Data (volt to strain in mm) after I did experimental works by using strain gage. What is the formula?
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.
