Material Modelling for Structural Analysis of Polyethylene
(University of Waterloo, 2007-01-17)The purpose of this work was to develop a practical method for constitutive modelling of polyethylene, based on a phenomenological approach, which can be applied for structural analysis. Polyethylene (PE) is increasingly ... -
Methodologies for Obtaining Reliable Indicators for the Environmental Stress Cracking Resistance of Polyethylene
(University of Waterloo, 2014-02-13)Environmental stress cracking (ESC) is one of the main, and probably the most common, failure mechanisms involved in polymer fractures. This type of failure is critically important as it occurs suddenly, without any visible ... -
Nonlinear Macromechanical Analysis of Polymeric Materials
(University of Waterloo, 2017-05-19)A new methodology for predicting the short term and long term responses of viscoelastic and viscoplastic materials is developed in this research. The methodology aims to predict the behaviour of viscoelastic/viscoplastic ... -
Wear and Boundary Lubrication in Modular Total Knee Replacements
(University of Waterloo, 2009-02-17)Wear of the polyethylene (PE) bearing surface and wear particle-induced osteolysis (bone resorption) can lead to failure of modular total knee replacements and make expensive revision surgery necessary. Gamma-in-air ...
