Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...

Dual-pressure tube hydroforming (THF) is a tube-forming process that involves applying fluid pressure to tube’s inner and outer surfaces achieve deformation. This study investigates the effect of dual-pressure loading paths on material formability tribological conditions. Specifically, pear-shaped triangular cross-sectional parts were formed using modes where inside tubular blank was alternated...

Abstract Side-notched tube structures made of superelastic material are increasingly being studied in surgical robotics as they can easily be integrated into instruments and offer the surgeon enhanced dexterity. Their simple design ability to achieve large bending angles small radii make them particularly suited for use constrained workspace surgery. Up now, however, no model has been able accu...

The measurement of acoustic material characteristics using a standard impedance tube method is generally limited to the plane wave regime below the tube cut-on frequency. This implies that the size of the tube and, consequently, the size of the material specimen must remain smaller than a half of the wavelength. This paper presents a method that enables the extension of the frequency range beyo...
