Abstract: This paper focuses on the analytical and numerical analyses to predict the dynamic response of fully clamped rectangular sandwich plates with fibre-metal laminate face-sheets and metal foam cores under blast loading. Based on the rigid-plastic material approximation with modifications, simple models are developed for the dynamic response of sandwich plates with fibre-metal laminate face-sheets. The so-called ‘bounds’ and the membrane mode solution for dynamic response of rectangular sandwich plates are obtained. The effects of the composite volume fraction, the ratio of metal layer strength to composite layer strength, relative density and relative strength on the dynamic response are discussed. The finite element calculation is carried out to study the dynamic response of the sandwich plates under blast loading. Good agreement is achieved between the analytical solutions and numerical results. This work provides the efficient method that reasonably captures dynamic response of the rectangular sandwich plates subjected to the blast loading.
