Composite mirror surface deformation due to lay-up sequences within quasi-isotropic laminates

Analytical and finite element prediction of Lamb wave scattering at delaminations in quasi-isotropic composite laminates

“…They are suitable for conservative industrial design because some elastic properties of QI composite laminates approximate the equivalent isotropic properties in engineering materials. Applications of QI composite laminates include composite mirrors of telescopes [26], aircraft structures [27] and spacecraft structures [28], etc. However, they have not yet been able to be assessed for defects using Lamb wave diffraction tomography, an assessment method which has been proved attractive in the context of SHM as it not only determines the existence and the location of the defect, but can also achieve the defect characterisation.…”
