Load Transfer Mechanics Between Trans-Tibial Prosthetic Socket And Residual Limb-Dynamic Effects, Xiaohong Jia, Ming Zhang, Winson Lee
Load Transfer Mechanics Between Trans-Tibial Prosthetic Socket And Residual Limb-Dynamic Effects, Xiaohong Jia, Ming Zhang, Winson Lee
Faculty of Engineering and Information Sciences - Papers: Part A
The effects of inertial loads on the interface stresses between trans-tibial residual limb and prosthetic socket were investigated. The motion of the limb and prosthesis was monitored using a Vicon motion analysis system and the ground reaction force was measured by a force platform. Equivalent loads at the knee joint during walking were calculated in two cases with and without consideration of the material inertia. A 3D nonlinear finite element (FE) model based on the actual geometry of residual limb, internal bones and socket liner was developed to study the mechanical interaction between socket and residual limb during walking. To …

An Investigation Into The Effects Of Heat Transfer On The Motion Of A Spherical Bubble, P J Harris, H Al-Awadi, Wee King Soh
Faculty of Engineering and Information Sciences - Papers: Part A
This paper investigates the effect of heat transfer on the motion of a spherical bubble in the vicinity of a rigid boundary. The effects of heat transfer between the bubble and the surrounding fluid, and the resulting loss of energy from the bubble, can be incorporated into the simple spherical bubble model with the addition of a single extra ordinary differential equation. The numerical results show that for a bubble close to an infiniterigid boundary there are significant differences in both the radius and Kelvin impulse of the bubble when the heat transfer effects are included.
