Abstract: Abstract This paper explores the basic mechanism of a multi-stopband negative stiffness composite column. The column consists of two parts: the base structure (concrete-filled steel tube (CFST)) and mass-spring-damper vibration absorbers (tungsten sphere-rubber). The local… read more here.

Abstract: Abstract This paper designs the laminate acoustic metamaterials with multi-stopband for structural-acoustic coupled system. The laminate acoustic metamaterials are composed of carbon-fiber-reinforced polymer (CFRP) and a periodic array of two degrees of freedom (2-DOF) mass-spring-damper… read more here.
