The finite element method (FEM) is widely accepted for the steady-state dynamic response analysis of acoustic systems. It exhibits almost no restrictions with respect to the geometrical features of these systems. However, its application is practically limited to the low-frequency range. An alternative method is the wave based method, which is an indirect(More)
The stroke-cam flapping mechanism presented in this paper closely mimics the wing motion of a hovering Rufous hummingbird. It is the only lightweight hummingbird-sized flapping mechanism which generates a harmonic wing stroke with both a high flapping frequency and a large stroke amplitude. Experiments on a lightweight prototype of this stroke-cam mechanism(More)

The presented paper focuses on a combined approach, using a new type of measurement setup, which has been specifically developed for examining the vibro-acoustic behaviour of lightweight panels and the Wave Based Method (WBM) for the numerical simulation of vibro-acoustic problems. The setup consists of a concrete cavity of 0.83 m³ which can host test(More)
This paper deals with design parameter variability of thermoplastic honeycomb sandwich panels and how this reflects on the dynamic behaviour of rectangular panels with free boundary conditions. ABSTRACT Honeycomb panels are sandwich structures. Their high specific strength and stiffness together with a low areal mass makes them ideally suited for ground(More)
A novel low temperature Cu-Cu bonding approach called the insertion bonding technique has been developed. This technique leverages on the initiation of high shear stresses at metal-metal contact interface, thus resulting in high plastic deformation, which is essential for strong bond formation. Through finite element studies, it is observed that the(More)
