How does temperature become a number

Submitted by Zhigang Suo on Sat, 02/21/2009 - 14:58

An essential step to “understand” thermodynamics is to get to know temperature: how temperature comes down as an abstraction from empirical observations, and how it rises up as a consequence of the fundamental postulate. I have just updated my notes on temperature. The beginning paragraphs of the notes abstract temperature from empirical observations. These paragraphs are posted here.

Composite Plate Modelling in Ansys 9

composite plate

Hi..

I'm new to Ansys.. I need to model a composite plate with a hole. It needs to have 5 laminated layers with different fiber orientations.

I've been through all similar queries here and have managed to understand how to model the layup (using the section -> shell method).

I have also modelled a sample plate with a hole.

I have also inputed the various material properties of each individual layer (through the Material Model editor).

BUT!! HOW DO I INTEGRATE THE LAYUP WITH THE SAMPLE PLATE ???.

How to Apply Torque in ANSYS

Submitted by hijazi on Fri, 02/20/2009 - 05:45

I want to do torsional analysis in ANSYS. The beam is hollow rectangular beam and the requirement is to rotate the beam in Z-direction. Can anybody guide me how to apply the torque?? I have applied the torque in the form of force but i am not satisfies with the results. Can anybody guide me how to apply torque??

Visualization of point displacements

hello,

I'm a new ABAQUS user. I wander if I can get the displacements of any point just by putting the mouse arrow near by it like what is done in the SAP program.

I'm searching for that option but till now didn't find it

Thanks a lot in advance

Viewing the displacement on the deformed shape

Hello,

I'm a new user of ABAQUS. I want to be able to view the displacements on the CAE deformed shape. Like to put the mouse arrow over a certain node and it writes the exact value of the deformations. (Like what can be done easily by the SAP program)

I just want to figure out how is that possible

Thank you in advance
