Abstract
Over the past decades, sandwich structures have shown impressive performances in impact resistance and damage tolerance, which has allowed their innovations in various disciplines to flourish. The birth of sewn sandwiches has given, on the one hand, elements with structural cores that participate in the resistance to transverse shearing and, on the other hand, sandwich skins that contribute to resisting forces from the same direction to achieve an assembly, giving the structure an optimal lightness. After evaluating the behavior of said structure against impact stresses, in this study, it is proposed to start by evaluating the effect of damage caused by impacts of different energies. Then, their influence on the structure's mechanical properties and its ability to undergo one or more new impacts will be checked. For this, by using a microscope, diagnostic tests have been carried out for each sample after the first impact, followed by characterization by non-destructive tests based on vibration analysis in order to examine and compare the properties of a healthy plaque with those of the affected plaques. The tests are carried out on samples of dimensions 150 × 200 × (1.5 + 20 + 1.5 = 23) mm3. The results obtained by using the specialized software PULSE have encouraged a second series of effects on these samples.
期刊介绍:
The International Review of Civil Engineering (IRECE) is a peer-reviewed journal that publishes original theoretical papers, applied papers, review papers and case studies on all fields of civil engineering. The scope of the Journal encompasses, but is not restricted to the following areas: infrastructure engineering; transportation engineering; structural engineering (buildings innovative structures environmentally responsive structures bridges stadiums commercial and public buildings, transmission towers, television and telecommunication masts, cooling towers, plates and shells, suspension structures, smart structures, nuclear reactors, dams, pressure vessels, pipelines, tunnels and so on); earthquake, hazards, structural dynamics, risks and mitigation engineering; environmental engineering; structure-fluid-soil interaction; wind engineering; fire engineering; multi-scale analysis; constitutive modeling and experimental testing; construction materials; composite materials in engineering structures (use, theoretical analysis and fabrication techniques); novel computational modeling techniques; engineering economics. The Editorial policy is to maintain a reasonable balance between papers regarding different research areas so that the Journal will be useful to all interested scientific groups.
