A pulsed laser loading technique for controlled dynamic loading of nanostructred materials
This thesis presents an improved laser loading technique for controlling and calibrating the stress waves created from this ultra-high loading rate technique. In the high-power pulsed laser loading technique, a laser produced compressive stress pulse passes through a substrate and reflects at a …

Mechanical loading and cartilage physiology
… it has been noted that altered joint loading and increased force may lead to cartilage degradation and increase the risk for the development of osteoarthritis (OA). This study investigated the cellular responses of chondrocytes to mechanical impact, and the effects of possible …

Trunk loading and back pain
… Stabilising the trunk during sudden, repetitive loading in everyday tasks, as well as during performance is important in order to protect against injury. Hence, reduced trunk stability is accepted as a risk factor for the development of back pain (BP). An altered activity pattern including …

Embankment performance under earthquake loading
Transportation networks are essential for a functional society and are a major component of civil infrastructure. The importance of a functioning network is heightened in a post-earthquake situation. More stress is placed on road networks to provide transportation for rescue, repair, and relief …

Edge fracture of AHSS sheets under out-of-plane loading followed by in-plane loading
… the fracture behavior under such a complex a loading path, the fracture initiation is modeled using the concept of a scalar damage indicator that consists of two parts which are accumulated at different stages. The first one is accumulated during the sheet blanking process, referred to as …

Loading of total hip joint replacements
Der totale Hüftgelenkersatz zählt zu den erfolgreichsten Operationen in der Endoprothetik. Jedoch ist das Patientenspektrum in den letzten Jahren immer jünger und aktiver geworden. Dadurch ist der Anspruch im Hinblick auf die Belastbarkeit und Lebensdauer dieser Implantate gestiegen. Bezüglich …

Trunk Biomechanical Responses during Sudden Loading
Back injury caused by sudden loading is a significant risk among workers who perform manual material handling tasks (MMH). Therefore, it is critical to understand the effects of influential factors on back injury risks during sudden loading, and to develop load handling strategies that can reduce …

Skeletal adaptation to reduced mechanical loading
… cues is poorly understood, particularly for unloading. Defining the fundamental mechanoregulation of bone adaptation is critical for the better understanding and mitigation of bone loss in astronauts as well as clinical conditions such as spinal cord injury, stroke, muscular dystrophy, and bed …

Muscle Loading Treatments for Achilles Tendinopathy
… quality of life. Physical therapy (eccentric loading) decreases the symptoms of tendinopathy and restores Achilles tendon functionality. However, the mechanism by which these mechanical stimulations induce healing is poorly understood. There is a clinically relevant motivation to better …

Combined mechanical loading of composite tubes
… tubes subjected to combined axial and torsional loading. An elasticity based analytical model was developed to predict stresses and deformations in composite tubes subjected to combined thermomechanical loading. Material nonlinearities were modeled using the Endochronic Theory. The effect of …

Hybrid experimental-numerical determination of the loading path to fracture in TRIP780 sheets subjected to multi-axial loading
… approach is taken to determine the loading path in various fracture experiments on TRIP780 steel sheets. In most mechanical experiments on sheet metal, the localization of plastic deformation precedes the onset of fracture. After the beginning of necking, the stress fields within the …

Energy-absorbing sandwich structures under blast loaDing
… more energy to a structure under blast loading relative to a structure without an energy absorbing faceplate. The objective of this work is to simulate non-uniform response of sandwich panels subject to blast loaDing This involves an investigation into the optimum design of a …

H-reflex changes with loading and unloading
… during lying, standing, weight lifting and unloading. This may influence the H-reflex. The purpose of this study was to measure the changes that might occur in the soleus H-reflex during such loading and unloading conditions. Twenty healthy volunteers (20-50y) with no history of significant …

Hydration and vocal loading on voice measures
<p>Vocal loading adversely affects the healthy larynx. The negative effects of vocal loading are thought to be exacerbated in dry environments, noisy environments, using non-habitual speaking patterns, and voice quality. Advancing age is also thought to be a risk factor for the negative effects of …
