A method of monitoring the structural integrity of a wind turbine blade 1 is disclosed. The blade 1 has at least two shell portions 2a, 2b, forming the outer surface of the turbine blade 1. At least one web member 3a, 3b connects the shell portions 2a, 2b in a transverse direction. The method comprises measuring a bending moment on the turbine blade 1 in a plane containing the longitudinal and transverse directions, measuring the transverse strain on the web member 3a, 3b at least one location, and comparing the measured transverse strain to an expected value for the transverse strain at the measured bending moment to provide an indication of debonding between the web member 3a, 3b and at least one shell portion 2a, 2b. |
