Hai, i am doing the robot silmulation in ADAMS View,now i struck in defining the math function to simulate the robot in 6 DOF/ workspace,, please tell me how to build spline function for different joints @ simultaneus.

Hey all,

I am simulating Lamb wave propagation in a plate and was wondering if anyone knows where I can find the criteria to chose the mesh size and the time increment size. Thank you.

Dear All,

We are planning to offer several PhD/Post-Doc positions at University of Strathclyde, Glasgow. The positions are expected to be in the area of computational mechanics including finite element analysis and panel methods. If you are interested, please send your current CV to oterkus@gmail.com .

Best Regards,

Important Questions on  

Applied Thermodynamics EME-401 for GBTU

Hey all,

I am trying to apply an Electric Potential B.C. to a surface. I want to use the dynamic/explicit analysis type, however, when I select that as my step type, the Electric Potential B.C. option disappears from the edit B.C. window! Is that due to a license limitation or an error I might have made in one of the definitions?

Thank you!

Hey all, 

I am not clear about two concepts: thermodynamics equilibrium state and steady state. It's easy to conceive of the following different two osmosis processes regarding thermodynamics equilibrium state and steady state, respecitvely.

Dear all,

I would like to receive an advice so as to partition in a properly way this hexagonal solid. I tryed to use partition cell extrude cell/sweep edge in the the curved  edge, but the solid it has not been partitioned.

thanks in advanced

In elementary mechanics textbooks, power lines are generally given as a typical example of a so-called “flexible cable”. However, in the design of these critical elements of a power grid  it is often necessary to take into account the conductor bending stiffness, or flexural rigidity. While relatively low compared with a bar having an equivalent solid cross-section, it does have some influence on a conductor response to wind excitation, in particular from the fatigue strength point of view.

Hi:

    I want to build a ellipsoidal model,how can i do  using abaqus?

How can post buckling analysis be carried out in ANSYS, when element Shell181 is used? what are the various methods and the procedure how to carry out the analysis ???

Dear all.

I'm currently doing some research concerning crack path prediction in brittle thin film.

But I'm struggled to find efficient way to do it.

In reality my case: stress is higly confined within semi infinite narrow rectangular strip patten and out of this rectangular, stress is very low or near 0 compared to stress within the pattern. Crack starts from left side end and propagates within pattern toward right end side of pattern. Crack show wavy propagation behavior with regular period and amplitude. 

Hi everybody,

I'm trying to model a 2D orthogonal cutting by Abaqus by using ALE method. I have some distortion of mesh in front of the cuuting noise so I try to define an eulerian surfaces around the cutting noise. 

One PhD student position available at the Department of Mechanical and Aerospace Engnieering of the University of Central Florida. Students with background in solid mechanics, computational mechanics and finite element analysis are particularly encouraged to apply. To apply, please send your resume and representative publications (if have) to Dr. Yuanli Bai (bai@ucf.edu).  The opening is until Spring 2014.
