Abstract Over decades, sandwich composite panels (SCPs) have been widely used to fabricate lightweight but strong structural components. However, composite sandwich structures are susceptible to impact damage, which may severely reduce the structural stiffness, stability, and load-carrying capacity[1, 2]. In order to enhance the anti-impact capacity of SCPs, a series of novel core structures[3-5] and filling materials[6-8] have been proposed and tested. One of them is the shear thickening fluids (STFs), which mechanical behavior changed from liquid to solid when subjected to high strain rate shear loading[7, 9]. For example, Fu et al.[10] filled the honeycomb cores of Carbon fiber reinforced… More >

Abstract It is of great significance to study the dynamic mechanical response of explosive charge to ensure the safety and reliability of weapon system. The manifold method is a novel numerical theory proposed in recent years to simulate the static and dynamic mechanical behavior of solid material. In the present work, a threedimensional numerical manifold software (3D-NMM) based on continuous-discontinuous coupled theory is developed to solve the impact response of PBX. Firstly, based on the 3D finite element topology, a four-node tetrahedral coverage system is established, and the shape function and displacement function, element stiffness matrix and inertial force matrix of… More >
