AB  - In	this	paper,	we	extend	the	Reissner-Mindlin	shell	theory	based	on	peridynamics method	proposed	in	[1]	
to	 the	stiffened	plate	and	explore	its	application	 to	engineering	problems,	several	examples	are	given	 to	
verify	its	effectiveness	in	 the	 dynamic	analysis.	The	 coupling	method	is	 used	in	 this	 paper	 to	model	 the	
stiffened	plate.	The	plate	and	the	stiffener	are	treated	as	two	independent	shell	to	calculate	the	velocity	and	
acceleration	 respectively,	 then	 the	 interaction	 between	 two	 parts	 of	 the	 stiffened	 plate	 is	 added	 at	 the	
coupling	particle	to	satisfy	the	continuity	condition.	The	non-local	peridynamics	theory	of	solids	provides	
an	 integral	 formula	 that	 can	 replace	 the	 traditional	 local	 continuum	 mechanics	 model	 based	 on	 partial	
differential	 equations,	 which	 has	 natural	 advantages	 for	 solving	 fracture	 problems	 with	 discontinuities.	
Several	numerical	examples	are	present	and	compared	with	the	numerical	results	of	other	methods.	The	
results	show	that	the	peridynamic	Mindlin	shell	theory	has	good	accuracy	and	stability	when	solving	the	
dynamic	response	problems	of	the	stiffened	plate,	which	lays	the	foundation	for	the	fracture	problems	of	
the	stiffened	plate	structure.
