AB  - How	the	plasticity	features	influence	the	fracture	behaviours	of	material	is	a	critical	question	but	remains	
far	 from	 well	 understood.	 To	 disclose	 this	 mystery,	 a	 multiscale	 plasticity-fracture	 coupled	 model	 is	
developed,	which	 considers	 the	 atomistic-scale	 dislocation	motion	mechanism,	 the	mesoscopic	 scales	 of	
discrete	 crack-dislocation	 interactions,	 and	 the	 continuum	 scale	 of	 crystalline	 plastic-fracture	 response.	
Body	center	cubic	(bcc)	material	is	chosen	as	an	example	to	demonstrate	the	effectiveness	of the	developed	
model	 due	 to	 their	 wide	 applications	 and	 their	 special	 plasticity	 features,	 such	 as	 strong	 temperature	
dependence	and	non-Schmid	effect.	Several	new	insights	about	the	fracture	behaviour	of	bcc	material	are	
gained.
