Abstract
New drafts of the ASTM standards propose to study stress corrosion cracking with an aim to determine K ISCC and da/dt = f(K I) for increasing loading (crack-opening displacements). The duration of the tests becomes smaller but the spread in data remains the same as in the case of constant loading and constant strains. The results of testing under increasing loading (opening displacement) strongly depend on the correct application of the method, especially on the proper choice of the rates of the process.
