    Experimental data

    Hi, I think you can't define an anisotropic hyperelastic material. In ANSYS, the hyperelastic material models assume that materials response is isotropic and isothermal. Regards.

    Spectrum Analysis - Off Resonance Results

    With SVTYPE,2 (acceleration versus freq.) you may be match the results...Be carefull of units, damping and your acceleration direction. You need the SVTYPE (to define the kind of excitation), SV (to define acceleration value, becarefull, the first value is the damping ration of your spectrum)...

    Spectrum Analysis - Off Resonance Results

    So, I understand that you are analysing your structure response with a mode superposition methode (not the full methode)...In this case I'm agree with you, you need to generate the mode shape before. I thought that when you've said :"2. Set up an Harmonic Analysis - leave settings at default" it...

    Spectrum Analysis - Off Resonance Results

    Sorry for the misunderstanding...it's not very easy sometimes to figure out the nature of our problems...never mind... About your last post: My Procedure: 1. Run Modal Analysis ---> It is not necessary for harmonic analysis (motion equation is directly solved...) 2. Set up an Harmonic...

    Spectrum Analysis - Off Resonance Results

    First: I apologize for my english....hope that you will understand me. My opinion about your problem: As far as I know, the principal steps for spectrum analysis are the followings: input: - frequency range for modal analysis (from fmin1 to fmax1) - spectrum data from frequence fmin2 to...
