Biomechanics of Oblique Lateral Impacts

A majority of laboratory-driven side impact injury assessments are made using post mortem human subjects (PMHS) under the pure 90-degree lateral mode. Because real-world injuries occur under pure and oblique modes, this study was designed to evaluate injury metrics and injury mechanisms with PMHS under the latter vector. Anthropometrical data were obtained and functional x-rays were taken. Spec...

Stress Concentration Factors in Spherical Vessels with Single Oblique Nozzle

Finite element method is employed to analyze the spherical vessel intersected by an oblique cylindrical nozzle. In this survey the stress and strain distributions on acute and obtuse sides of the connection under internal pressure are studied widely although axial and moment loadings on the nozzle are also studied briefly. Stress concentration factors for a wide range of geometrical ratios in t...

Opercular jetting during fast-starts by flatfishes

When attacked by predators, flatfishes perform fast-starts that result in a rapid take-off from the ocean bottom on which they lie. High-speed video recordings of the blind side of flatfishes indicate that they expel a coherent jet of water from the blind-side opercular valve during take-off. Buccal pressure recordings in winter flounder (Pseudopleuronectes americanus) show that a buccal pressu...
