Abstract

An electronic stress monitoring device ( 1 ) is provided that is arranged to detect and record measurements of stress experienced by a structure ( 2 ) to which the stress history unit is attached, with the measurement and recordal of stress occurring at substantially the same location. The stress monitoring unit ( 1 ) is also arranged to process the detected readings of stress to determine when significant structural events are occurring within the structure ( 2 ) to which it is attached. Data indicative of these events are recorded within the stress monitoring device ( 1 ). Periodically data recorded within the stress monitoring device ( 1 ) is obtained by data reader ( 4 ) and then transmitted to a computer ( 6 ) for subsequent analysis.
