Contact Stress Gradient Detection Limits of Pressensor Film
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fuji Pressensor film has been widely used for measurement of contact stresses in articular joints. In relatively smooth contact fields, measurement errors are reported to be in the range of ...
Pre-Collapse Stress Redistributions in Femoral Head Osteonecrosis—A Three-Dimensional Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional finite element analysis is used to explore the influence of several lesion characteristics upon mechanical stress distributions in segmentally necrotic human femoral heads. Variables ...
Oil Conservation in Home Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Field studies of the oil consumption characteristics of oil-fired residential heating systems have been carried out in several homes in a severe winter climate. Daily recording of the fuel ...
Sulphur Neutralization by Lignite Ash: Pilot-Scale Combustion Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pilot-scale research boiler (750 kg steam/hr) has been used to study the degree of sulphur neutralization during combustion experiments with three lignites. A series of four closely controlled ...
Factors Influencing Accuracy of Screw Displacement Axis Detection With a D.C.-Based Electromagnetic Tracking System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent technical improvements and cost reductions in electromagnetic motion tracking systems invite their application to motion axis determination in the surgical setting. After evaluation of the ...
Vanadium Pentoxide Deposition From Combustion Gases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rate of deposition of vanadium pentoxide vapor from combustion gases produced by burning a liquid fuel (kerosene with added vanadium ethyl hexoate) under controlled mixing-history conditions ...
A Dynamic Finite Element Analysis of Impulsive Loading of the Extension-Splinted Rabbit Knee
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic nonlinear finite element model was developed to study juxtarticular stresses in the splinted rabbit knee, an established laboratory model for creating osteoarthrosis due to impulsive ...
A Parametric Design Evaluation of Lateral Prophylactic Knee Braces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Six major mechanical design variables characterizing single-upright lateral prophylactic knee braces were studied experimentally, using a generic modular brace (GMB). Impulsive valgus loading tests ...
A Three-Dimensional Computational Simulation of Some Sources of Measurement Artifact in Microvascular Pulsed Ultrasound Doppler Velocimetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent applications of 20 MHz pulsed ultrasound Doppler velocimetry (PUDVM) in microsurgical research have necessarily employed piezoelectric crystals whose diameter is not negligible compared to ...
