Structural health monitoring of fibre metal laminates under Mode I and II loading
10.1016/j.compositesa.2018.01.008 2018-01-08 Delamination is one of the most common defects in FRP and occurs due to low interlaminar strength. Such defects are difficult to detect and lead often to catastrophic failure of the composite. In this work a new approach of a multi-functional FML for structur... |
