Hello All,
I'm new on this forum and my english is no to perfect, so apologize for mistakes.
I'm trying to perform harmonic reponse analysis in direct method.( I have nolinear materials )
Is it possible to apply load as acceleretion vs frequency or only by concentrated force? ( I could create amplitude vs frequency, but how to know mass ? from .dat file after modal analysis ?) Do i using good type of analysis to achive my goal ? ( steady-state dynamics)
About model, in one side i have fixed support, on second side some excitation amplidude, measured in lab test.
I would like to check and make correlation on amplification factor ( amplitude of acc divide by amplitude of response on some node at my model.
I will appreaciate all useful tips
thanks
