Crack growth of aluminum A-alloy due mechanical fatigue efforts. Alea.A is a data frame composed of 262 rows y 3 columns.
This data frame is composed of the following columns:
21 vectors with times or cycles corresponding to each specimen (overall 262 cycles).
21 vectors with the crack lengths corresponding to each specimen.
21 different specimens, each one repeated the number of elements of "cycles" or "cracks".
Alea.A is composed of the crack length growth and number of cycles of 21 different specimens. It is detailed in Hudak et al. (1978) and referred by Meeker and Escobar (1998) in table C.14.
