RISA Pressure Distribution Transducer for In-Vitro Static Measurements in Synovial Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The basic features and the performance characteristics of a transducer to measure in-vitro static pressure distribution at the articular interfaces of intact synovial joints are described. Pressure ...
Design and Performance of a Modified Buckle Transducer for the Measurement of Ligament Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The basic features of a modified buckle transducer for the direct in-situ measurement of tension in ligamentous or tendonous tissues are described. The slender shape of the modified design ...
A Simple Unconstrained Dynamic Knee Simulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of a simple dynamic knee simulator is described. In the simulator the joint dynamics are reproduced in-vitro in a knee specimen by controlling the time-histories of the tensions in ...
Design and Development of an Unconstrained Dynamic Knee Simulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic knee simulator has been developed to allow in-vitro investigation of the mechanical response of the joint corresponding to dynamic functional activities, e.g., walking. In the simulator, ...
In-Vitro of Measurement of Static Pressure Distribution in Synovial Joints—Part I: Tibial Surface of the Knee
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this first part of a two-part paper, the results of measurement of static pressure distribution on the tibial surface of the knee are presented. Results with intact menisci have been ...
The Role of Secondary Variables in the Measurement of the Mechanical Properties of the Lumbar Intervertebral Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general method is proposed for the testing of the structural properties of lumbar intervertebral joints. The apparatus designed includes a loading jig capable of applying any wrench resultant ...
Correlation of Patellar Tracking Pattern With Trochlear and Retropatellar Surface Topographies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study was aimed to test the hypothesis that in the knee extension range 100 to 30 deg, the patellar “out-of-plane” tracking pattern is controlled by the passive restraint provided by the ...
Effect of Misalignment on the Characteristics of Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the renewed interest in the effect of misalignment on the dynamic characteristics of journal bearings, this paper presents a study of the effect of misalignment on the dynamic characteristics ...
Thermal Modeling of Polymerizing Polymethylmethacrylate, Considering Temperature-Dependent Heat Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A methodology for the modeling of unsteady heat conduction in polymethylmethacrylate (PMMA) during its exothermic polymerization is presented. The emphasis is on the formulation of a model for ...
In-Vitro Measurement of Static Pressure Distribution in Synovial Joints—Part II: Retropatellar Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This second part of a two-part paper is concerned with the measurement of static pressure distribution on the retropatellar surface. The study has been performed in a loading apparatus designed ...
