Abstract
Many studies have demonstrated for composite structures such as aerospace components the peak force of impacts can be correlated to damage. Hence, techniques able to estimate the impact forces are being investigated. The present paper deals specifically with the inverse problem of identification of impact forces on isotropic and composite panels given the dynamic response of Macro Fiber Composite (MFC) sensors bonded to the components. First a Semi Analytical Finite Element (SAFE) approach is employed to predict the frequency response and time history response of the MFC sensors assuming an impulse force excitation. Subsequently, the impact force is estimated updating the force time history assumed in the SAFE by minimizing the difference between numerical and experimental signals from MFC sensors. Such procedure has been used in isotropic and composite plates. Impact forces generated using impact hammers and different ice projectiles launched with gas cannon on panels have been identified.
