Abstract
A method of monitoring corrosion in a metal sample comprising applying a physical stress to one or more metal samples, placing the metal sample under stress in a sealed vessel, adding one or more fluids to the vessel, measuring the strain on the metal sample over a specified time interval, controlling the environment inside the vessel, calculating the rate of change of the strain measurement over the specified time interval, recording the rate of change of the strain measurement, calculating a moving average of two or more previously recorded rates of change of the strain measurement, and monitoring the moving average to detect damage to the metal sample.
