Why is stress due to centrifugal force much higher in dynamic explicit analysis?

04 April 2018 1 3K Report

Hi all!

I have a question about dynamic explicit analysis.

I don't understand why is stress due to centrifugal force in dynamic explicit analysis much higher value than in static general analysis. I've made two models, each with same rotational velocities , dimensions and material properties. When I try to run analysis in static general/dynamic explicit I get totally different results in terms of stress. Does anyone know why?

centrifugal force dependent to the mass&angular velocity&radius of rotor.when the mass is increase this force increase
