Step response and resonant frequency
Dear sir, I am modelling a piezoresistive pressure sensor. I want to now study the structure when a step load is applied , meaning pressure is applied on the top surface all of a sudden in full...

Hi all frequencies are the resonant frequencies, but if you apply a pressure change over the full thin membrane you excite mostly the fundamental mode (first mode) to apply a step pulse, use the...

Dear sir, Thank you for your reply. You have mentioned that only the first mode will be present as it is a thin membrane. But in my structure the membrane is thick (0.21mm) , and its side is (0.75mm)...

Hi indeed if you are looking for a transient (sudden pressure rise) you should work with a time dependent solver, and deine a step function "Definitions - Function - Step" node check the advanced...

Dear Sir, Thank you for your reply. I wanted to clarify a few more things. I am trying to get a sudden response so why should i use smooth step function ? Can i do it without using step ? I am getting...

Hi all or a combination of all of the frequencies are the "resonant frequency". Mostly the first one is the "predominant" one, but that depends on the excitation. It is very model (shape) dependent and...
