(a) Plot showing a decline of activation area for crack growth versus CTE of the glass, indicating indirectly that the parameter A* decreases with increasing reactivity of the glass caused by higher alkali and alkaline earth oxide contents. (b) Dependence of the activation area with G, according to the data shown in Fig. 2. The lines are theoretical boundaries ( A=mkT/2G) taking m from the fittings summarized in Table 2.
