Abstrac+-Crack closure experiments were conducted on 6061-T6 Al-alloy, using COD gauge for various overload ratios (1.67, 1.88 and 2.06) and different prestrains (0, 3 and 6%). On the basis of these experiments some power laws are developed. The delay period after application of single overload is a
