Deflection of centrally loaded thin circular elastic plates on equally spaced point supports

Abstract

Bassali 's ge ne ral th eo ry fo r the fl exure of th e thin c irc ul a r elastic pl a te suppo rted a t a n a rbitrary numbe r of points a nd subj ec ted to tran sverse load ove r a n ecce ntri c circle is spec ialized to th e case of a centrally load ed pla te s upporte d at points equally s paced on a c ircle co nce ntri c with th e ce nte r. Simplified me thod s fo r approximating th e res ults predi cted by th e more complic ated theo re ti cal ex pressions for defl ec ti o n are prese nted along with th e ex pe rim e ntal res ult s from 138 tes ts . Both th e ex pe rimental res ults a nd th e simplifi ed equati ons a re co mp a red with the th eo ry and agree me nt is fo und to be good.
