ABSTRACT = {In	order	to	evaluate	the	blast mitigation	effect	of	polyurethane	foam	in	cylindrical	explosion	containment	
vessels (CECVs),	a	three-dimensional	numerical	simulation	model	was	established.	The	Structured	Arbitrary	
Lagrange-Euler	 (S-ALE)	 algorithm	 was	 applied	 in	 current	 simulations	 to	 define	 the	 coupling	 contact	
between	 TNT	 and	 Lagrange	 algorithm.	 The	 numerical	 model	 was verified	 by	 comparing	 the	 dynamic	
deformation and	permanent	deformation of	the	experiments.	Based	on	the	numerical	simulation	model	after	
verification,	 the	 influence	 of	 polyurethane	 foam	 filling	 inside	 CECVs	 on	 the	 mitigation	 effect	 was	
investigated.	The	results	revealed	that	compared	with	the	ALE	algorithm,	the	numerical	simulations	based	
on	the	S-ALE	algorithm	were	in	good	agreement	with	the	experiments	without	leakage.	The	fully	covered	
polyurethane	 foam	had	a	slight	negative	effect	on	 the	deformation	of	CECV,	which	may	be	caused	by	 the	
reduction	of	explosion	space [1].	However,	the	bulk	polyurethane	foam	with	a	specific	size	can	effectively	
reduce	 deformation,	 due	 to	 the	 shadow	 formed	 by	 blast	 wave	 diffraction [2,3].	 There	 was	 a	 significant	
positive	correlation	between	the	thickness	of	polyurethane	foam	and	the	blast	mitigation.	The	conclusion	
provides	a	 reference	 for	 the	numerical	 simulation	and	 the	improvement	methods	 of	CECVs	 subjected	 to	
internal	blast	loading.},
