DOI: 10.1016/j.ijnonlinmec.2020.103632
Abstract: Abstract Aiming to isolate disturbance vibration for heavy payloads with low frequency, a novel hydro-pneumatic near-zero frequency vibration isolator is proposed, which possesses high-static and low-dynamic (HSLD) stiffness. And different from most isolators existing previously,… read more here.

DOI: 10.1088/1367-2630/abef28
Abstract: Metamaterials have demonstrated great potential for controlling wave propagation since they are flexibly adjustable. A new one-dimensional metamaterial model with both a negative effective moment of inertia and negative effective stiffness is proposed. A negative… read more here.
