This article is devoted to the assessment of efficiency using wall sandwich panels with mineral wool core, sheathing made galvanized steel a polymer coating, used as blast-relief panels. The presents developed seating unit for panel at moment explosion energy influence. As result experiments carried out, when an excess pressure no more than 3.0 kPa in room reached, safety shut-off devices ensur...

This work examines the performance of composite panels when subjected to underwater impulsive loads. The scaled fluid–structure experimental methodology developed by Espinosa and co-workers was employed. Failure modes, damage mechanisms and their distributions were identified and quantified for composite monolithic and sandwich panels subjected to typical blast loadings. The temporal evolutions...

The sound insulation capacity of traditional boards is limited by the law mass, and any improvement in contradicts demand for light weight. In order to overcome this shortcoming, a lightweight particle reinforced gradient honeycomb sandwich panel proposed achieve insulation. calculated based on transfer matrix method. accuracy theory verified through finite element simulation, influence materia...
