A refined method for calculating three-layer structures (TLS) in the zones of edge effects is considered, taking into account the influence of the approach of load-bearing layers on the stress-strain state (SSS) of the TLS. To determine the SSS of TLS, approximating strain distribution functions in the filler are used, which should correspond to the actual work of three-dimensional structures. Keywords: three-layer structure, load-bearing layer, approach of layers, approximating function, filler. hairulla213@mail.ru

The results of experimental studies of the effect of concentrated dynamic loads on a three-layer structure with glass fiber filler are presented. A comparative analysis of the obtained results with theoretical data is carried out. Keywords: three-layer structure, striker, bearing layer, fiberglass, impact loading. hairulla213@mail.ru
