Harmonic response - BEAM elment - ANSYS Workbench

[Tiagomota]

Hello everybody.
I'm trying to simulate a harmonic response on a structure with beam element. I have results for deformations but when I try obtain the equivalent stress (Von Mises) the program give a green check but on "geometry" doesn't show anything (except the structure), in fact program doesn't calculate any stresses. Ansys allows to calculate stresses when I'm using harmonic response?
Another question: Ansys doesn't allows to calculate deformation/stress with periodic solicitions correct?

Thanks a lot.

Best Regards.

"Ansys allows to calculate stresses when I'm using harmonic response?"

No. The program is just finding eigenvalues and eigenmodes, there is no displacement or load considered, thus no stress outputs.

"Another question: Ansys doesn't allows to calculate deformation/stress with periodic solicitions correct?"

If doing a full time integration, you can get displacements and stresses.

Sorry I disagree with you. On harmonic response I can considered forces... I think you are confused with modal and harmonic response....

Thanks.

Best Regards.

Dear all,
I want mode shape and natural frequencies of composite cantilever beam by using MATLAB program. The composite beam made up of 3 layers of different material ( Aluminium,rubber and steel) with different Young's modulus and different density. try to reply on hujarepp @gmail.com . please tell me how prepare MATLAB program for such a composite cantilever beam. please do needful help.
