Dear All,

I am trying to simulate a milling operation with temperature. This is a 3-D simulation. I am using C3D8T element type. It has 1,2,3 and 11 degree of freedom. Can you please help me in choosing an other solid element type which has additional 4,5 and 6 degree of freedom. Therefore, I need a solid element type with 1,2,3,4,5,6 and 11 degree of freedome. I get this warning:  ***WARNING: DEGREE OF FREEDOM 4 IS NOT ACTIVE ON NODE 14 INSTANCE WORK-1 - 

             THIS BOUNDARY CONDITION IS IGNORED

Thanks

Here is how I have carried out the forced vibration
simulation. After an “intial step”, I chose “Linear Perturbation” to first
extract the natural frequency. My next step was “Modal Dynamics”. I then
applied the load in the form of a sine wave under the same step. I have an
isotropic material. When I try to submit the job, I received following warning:

Dear all

I am trying to plot the dispersion curbve for wave propagation in an ALuminum beam under S0 and A0 lambwave.  My simulation has completed and I thin the results are reasonable as long as visualization is concerned.

I am trying to plot dispersion curve for these two waves using Abaqus outputs. As far as I know I need to use Abaqus outputs such as displacement or velocity for calculation of wave speed.

1- How would I calculate wave speed by Abaqus outputs and is this calculated wave speed the phase velocity or group velocity ?

Dear Friends,



Please find attached the new 2012-2013 issue of the ASME Applied Mechanics Division Newsletter. Enjoy!
