Dear all,

Two fundamental concepts from thermodynamics are that systems try to minimise their potential energy, whereas the tendency is to maximise the entropy (ofcourse I am not at all precise in the above statement, but I hope I am able to convey the matter.  Further, the two can be combined in the form of a free enrgy as applicable to the system under consideration).

I'm looking for a good quality master's degree in computational mechanics. I currently live in Australia, and would prefer to study in Europe (must be an English based program as well). I have undergradaute degrees in mechanical engineering and computer science.



Two main degrees that stick out for me are the ones at the University of Stuttgart, and the Technical University of Munich.

Hi everyone,

 some one please help me! I need some standards names and title for a course project.

I am searching for standards for testing pressure drop in pipes, valves, sight glasses and other hydrulic components. also i need standards for testing pumps too(specially diapheragm pumps) . i used google, but i didnt find anything useful, please help me. 

Hello everyone,

I am studying fracture of polymer composites.

I had a question I want to relate fracture toughness of composite to the composite stress-strain curve found from simple tensin test(on samples with no notch or pre-existing crack), can anyone give me a hint , how to do it?

Dear Abaqus user

I am modeling a post-tensioned concrete pier with 4 part:

-concrete foundation,pier,cap(C3D8R) and tendon(wire,B31)

 I input prestress force by predefined file,stress in initial step.The first step is static,General to find equilibrium.

 I embeded the beginning & the end of wire in foundation & cap. contact between (foundation,pier) & (pier,cap) is hard normal contact and the tangential behavior is penalty.

It is not recommended to Invert a Matrix in Numerical Analysis. Solving with Factorization methods (L.U, L.D.Lt, ..) is better than Solution with Direct Inverse. This is due to Numerical Errors (roundoff) and/or ill-Conditioned problems. In case of you need to use an Inverse, you are advised to take care about using existing algorithms which can't be exact in all applications.
