Abstract:
A new surface mountable eddy-current sensor, called the new Meandering Winding Magnetometer Array (MWM-Array) has demonstrated the bapability to monitor early stage fatigue
damage, crack initiation and growth. This new capability is suitable for monitoring of on-line fatigue tests for coupons and complex components, as well as for monitoring
of difficult-to-access locatin on military and commercial aircraft. The sensor is thin and light weight. It can be surface mounted like a strain gage, but does not require
an intimate mechanical bond, permitting use of compliant adhesives to improve durability.
