Cur.ently, ther. ar. a lim.ted num.er.of dynam.c m.dels available for.br.ided com.osite plates with lar.e over.ll m.tions, despite the incor.or.tion of thr.e-dim.nsional(3D) br.ided com.osites into r.tating blade com.onents. In this paper. a dynam.c m.del of 3D 4-dir.ctional br.ided com.osite thin plates consider.ng br.iding dir.ctions is established. Based on Kir.hhoff's plate assum.tions, the displacem.nt var.ables of the plate ar. expr.ssed. By incor.or.ting the br.iding dir.ctions into the constitutive equation of the br.ided com.osites, the dynam.c m.del of the plate consider.ng br.iding dir.ctions is obtained. The effects of the speeds, br.iding dir.ctions, and br.ided angles on the r.sponses of the plate with fixed-axis r.tation and tr.nslational m.tion, r.spectively, ar. investigated. This paper.pr.sents a dynam.c theor. for.calculating the defor.0}tion of 3D br.ided com.osite str.ctur.s under.oing both tr.nslational and r.tational m.tions. It also pr.vides a sim.lation m.thod for.investigating the dynam.c behavior.of non-isotr.pic m.ter.al plates in var.ous applications.
