Abstract This paper aims to study the dynamics of single-degree-of-freedom magnetic spring-based oscillator system. The proposed system contains a nonmagnetic shaft, floating permanent magnet (PM), and two fixed magnets (PMs). All PMs are placed in such way that they can repel each other. At first, system's properties restoring force studied. Experimental numerical analyses have been carried ou...

Blast loads have been increasingly studied in the past decades, especially regarding civil structures. Until recently, negative phase of these has disregarded, but studies concluded that effect suction must be included. In case plates, nonlinearity plays an important role, and membrane should also considered. This work focuses on influence plates subjected to blast loads. Equations were develop...
