ABSTRACT = {It	 is	 a	 textbook	 knowledge	 that	 the	 mechanical	 properties	 of	 crystalline	 solids	 are	 determined	 by	 the	
performances	of	 their	defects	under	certain	circumstances	of	external	stress	and	 temperature.	However,	
such	a	belief	in	crystals	meets	difficulty	in	amorphous	solids,	in	which	the	concept	of	defect	is	hard	to	define.	
In	 this	 talk,	 I	 would	 like	 to	 talk	 about	 the	 unusual	 structure-property	 of	 amorphous	 metals	 from	 three	
different	perspectives	– in	terms	of	their	structural,	vibrational	and	deformation	characteristics.	We	try	to	
build	a	super	structure-property	relationship	in	the	general	amorphous	solids	by	machine	learning	strategy	
after	we	realized	that	their	no	direct	one-to-one	correspondence	in	amorphous	metals’	functions.	Then	we	
study	and	understand	the	deformation	behaviors	of	amorphous	metal	starting	from	phonon,	which	present	
abundant	of	novel	phenomena	compared	to	crystals.	Finally,	the	 fracture	of	amorphous	metals	via	either	
shear	 banding	 or	 necking	 after	 characterized	 by	 a	 new	 fracture	 criterion,	 which	 is	 constructed	 by	 the	
geometry	and	bonding	nature	of	amorphous	materials.	All	the	new	knowledges	are	obtained	from	atomistic	
simulations,	 which	 is	 targeted	 to	 provide	 a	 quantitative	 structure-property	 relationship	 in	 the	 generic	
amorphous	metals.},
