Název v původním jazyce

Crack growth in Fe-2.7 wt% Si single crystals under cyclic loading and 3D atomistic results in bcc iron

Popis výsledku v původním jazyce

To search for correlations between experiments on macro-level and atomistic results on nano-scale,new experimental results from fracture tests under cyclic loading performed at room temperature on bcc iron-silicon single crystals with edge crack ð 110Þ[110] (crack plane/crack front) are presented. The crystals were loaded in mode I with stress ratio R = 0. Crack growth Da under various values of the applied stress intensity DKA and acoustic emission response were monitored simultaneously.Experimental results comply with the basic predictions on fatigue crack growth following from continuum modeling and with molecular dynamic (MD) simulations in bcc iron. MD and experimental results can be described by very similar values of the Paris exponents although different length scales are treated in the two methods.
