The criterion shows cracking is mor

The criterion shows cracking is more likely under faster straining. At the same cooling rate dT/dt, a higher deformation rate Vlocal (Eq. (10)) or strain rate delocal/dt (Eq. (11)) can exceed the RHS more easily to cause cracking. Faster straining allows more strain to accumulate in the same period of time. The criterion also shows cracking is more likely at slower cooling. At the same deformation rate Vlocal, a lower cooling rate dT/dt makes the growth term and hence the RHS smaller and hence easier to exceed to cause cracking.
