Two series of experiments are performed to investigate the dynamic response of various essential components of a class of sandwich structures, under high-rate inertial loads. One consists of dynamic inertia tests and the other involves dynamic impact tests. A split Hopkinson bar apparatus is modified and used for these experiments. First, the energy-absorbing characteristics of the plate materi...

Abstract This study is focused on the low-velocity impact response of 3D plate-lattices fabricated via stereolithography additive manufacturing (AM). Elementary (SC, BCC and FCC) hybrid (SC-BCC, SC-FCC SC-BCC-FCC) configurations were tested effects energy, relative density, plate-thickness, multiple impacts angle dynamic crushing behavior energy absorption characteristics analyzed. The experime...

In the vast Algerian Sahara, the climate is typically desert, characterized by heat and dryness all year, which contributes to a very pronounced aridity. The aim of this study is to investigate the impact of this arid environment on automotive paints. Four paint samples with different durations of use were tested. Initially, a visualization of the surface condition by optical microscopy and...
