I did the analysis for the snap-through of curve beam (this is a bistable mechanism) and using both "beam3 element" and "plane82 element" to find the force-displacement. However the obtained f-d curves are different between these two element.
May anyone give me some suggestions to deal with my problem ?
Thank you !
Use enough element segments for beam3
Use enough element segments for beam3 then we will have a result the same as plane82
