Development of the Corrected Force Analysis Technique for laminated composite panels

The aim of this paper is to propose a methodology for identifying the pressure field applied on laminated composite plate from its measured vibration response. general framework study Corrected Force Analysis Technique (CFAT), which was previously used isotropic plates. This method estimates spatial derivatives equation motion with finite difference scheme and corrects bias error generated by approximation. presents an extension technique deal panels. In first instance, has been expanded allow identification 5 that compose such structures. correction, considered in wavenumber domain, also adapted now calculated numerically. second effect measurement noise treated implementation regularisation based adaptation size as function frequency. Numerical simulations contact-less measurements have conducted different carbon fibers Results are presented terms identified fields input force magnitude.
