Finite Element Stress Analysis of a Spinal Segment
A large number of factors need to be determined to understand the biomechanics of a surgical procedure about the lumbar spine. Some of these factors are amenable to experimental investigations...
In-Vitro Measurement of Static Contact Pressure Distribution in Synovial Joints
The objective of this presentation is, at first, to review the various approaches to the measurement of contact pressure distribution in synovial joints, and then to describe the development...
Biomechanics of Local Articular Incongruities
Abnormalities of intra-articular contact near sites of local surface incongruity are frequently associated with secondary osteoarthrosis. We here review a series of experimental and computational...
Vibration of Plates with Corner Stress Singularities
A method of analysis is presented to determine the free vibration frequencies of plates having corner stress singularities. Displacements are assumed in the form of polynomials, and corner...
Cumulants of the Nonlinear Combination of Independent Random Variables
A random variable of interest is often the sum of linear or nonlinear combinations of many independent random variables. In calculating the statistics of this random sum, advantages of...
