Abstract
Experimental and theoretical investigations by the method of acoustic emiss ion and atomistic simulations by a molecular dynamics technique show that b rittle-ductile transition in alpha-iron is very sensitive to loading rate a nd that the character of acoustic emission is different when different proc esses operate at the crack tip. A self-similar concept for comparison of ex perimental and atomistic results is proposed for fracture tensile tests.
