Zusammenfassung:This paper addresses the problem of the dynamic response in bending of flat sandwich panels exposed to time-dependent external blast pulses. The study is carried out in the context of an advanced model of sandwich structures that is characterized by anisotropic laminated face sheets and an orthotropic core layer, and a closed form solution of the dynamic response to a variety of blast pulses is provided. A detailed analysis of the influence of a large number of parameters associated with the particular type of pressure pulses, panel geometry, fiber orientation in the face sheets and, presence of tensile uni/biaxial edge loads on dynamic response is carried out, and pertinent conclusions are outlined.
