Epidemiological studies have shown a relatively strong association between occupational lower back pain (LBP) and long-term exposure to vibration. However, there is limited knowledge of the impact of vibration and sedentariness on bone metabolism of the lumbar vertebra and the mechanism of bone-derived LBP. The aim of this study was to investigate the effects of vibration in forced posture (a s...
Vibration based Structural Health Monitoring of a Composite Plate Structure with Multiple Stiffeners
A vibration based damage identification method is investigated experimentally. The dynamic response of an intact and a locally damaged 16–layer unidirectional carbon fibre PEKK reinforced plate structure with two stiffener sections is considered. A forced–vibration set–up, including a laser vibrometer system, is employed to measure the dynamic behaviour. The feasibility of the two–dimensional M...
