    material damping

    Hi caemagic, Thank you for your reply. This relationship which you have specified holds good for dampers using a viscous fluid. Can i use the same relationship as it is more of material dependent damping (o-ring) which is primarily amplitude dependent rather than velocity dependent ( as in the...

    material damping

    hi everyone, I have values of damping for a single degree of freedom system interms of damping ratio for a particular mode of vibration. the damping is purely contributed by a rubber material due to its material property. How do i convert this ratio into equivalent material damping coefficient...

    mode indicator function

    what is the prime difference between mode indicator function and power spectrum of mode indicator function ? from certain experimental data obtained through impact testing, i could see that there is a variation between the modes indicated by both these methods... why is that happening???

    Combin14 element

    Is it possible to model a single degree of freedom system using combin14 element and define material dependent damping for the same element as a real constant in ANSYS Thanks

    strain energy density functions

    what are strain energy density functions? how are they useful in hyperelastic models?can't the same function be used in linear models in analysis ?

    modal analysis using ansys workbench

    I am trying to do a modal analysis of a single degree of freedom system in ANSYS. Here, in this system, a cylindrical mass is suspended between two O-rings (1 on each end). I want to capture the behaviour of this mass for various amounts of squeeze given to the O-ring. A separate cylinder is...
