✦ Synopsis

The experimental results show that (I) X, of two thin sheet aluminum alloys are valid; they_ are I?, = 201.39 kg/mm"* and l?,, = 208.31 kg/mm"2 of Lyl22c2(1), K, =226.18kg/mm"2 and K,,= 234.55 kg/mm3" of Lc4 -cs; (2) the R-curves of the four thin sheet aluminum alloys are independent of the initial crack length of specimen; (3) for different initial crack lengths the crack growth Aa is not a constant.
