註釋

Results of an experiment designed to study the effect of several variables on subcritical crack growth rate of a high-strength steel in a water environment are presented. Environmental variables included temperature, pH of the liquid environment, electric charging, and the combined effect of pH and electric charging. Tapered double cantilever beam specimens were designed so that the level was maintained constant at a constant load and independent of crack length. Thus steady-state crack growth measurements were possible in constant load and constant environment experiments. With this specimen design, it was possible to make a series of measurements that covered the entire range of effects of a particular variable using only one specimen. (Author).
