RISDevelopment of a Variable Stiffness Over Tube Based on Low Melting Point Alloy for Endoscopic Surgery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Instruments used in endoscopic surgery (colonoscopy surgery or natural orifice transluminal endoscopic surgery (NOTES)) are flexible to be advanced in human body. However, when the end of the instrument reaches the target, ...
Effect of Nozzle Outlet Type on the Flow Field Velocity and Impact Pressure of High-Pressure Water Jet Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Water jet peening can effectively improve the fatigue strength of metal materials, and the outlet shape of nozzle greatly affects the effect of water jet peening. In this paper, the effects of nozzle outlet shape on water ...
A Novel Structure of a Less Invasive Forceps to Realize Linear Clamping for Endoscopic Surgery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Safety is always a commonly concerned issue during the development of minimally invasive surgery for more than 30 yr. For the absence of force feedback in conventional forceps, excessive pressure may be applied on tissues ...
Residual Stress Distribution in a Dissimilar Weld Joint by Experimental and Simulation Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dissimilar welding between carbon steel and stainless steel is widely used in power plant. A lot of stress corrosion cracking (SCC) have occurred in the weld joint, which are affected greatly by residual stresses. This ...
Effect of Impact Pressure on Reducing the Weld Residual Stress by Water Jet Peening in Repair Weld to 304 Stainless Steel Clad Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stainless steel clad plate manufactured by explosive bonding is widely used in the chemical industry, but cracks are often initiated in the clad layer. Repair welding is a popular method to repair the cracked zone. But ...
Self-Centering Rocking Composite Frame Using Double-Skin Concrete-Filled Steel Tube Columns and Energy-Dissipating Fuses in Multiple Locations
Publisher: American Society of Civil Engineers
Abstract: Self-centering rocking frame structures are high-performance seismic-resilient structures that exhibit damage in specified locations and keep the majority of structural elements elastic. Their recentering mechanism efficiently ...
Improving Workplace Hazard Identification Performance Using Data Mining
Publisher: American Society of Civil Engineers
Abstract: Hazard identification, as the first major step of risk management, is a crucial activity for reducing accidents and other related losses. However, recent research has revealed that a large proportion of workplace hazards ...
Effect of Temperature Fluctuation on Creep and Failure Probability for Planar Solid Oxide Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creep and failure probability of a planar solid oxide fuel cell (SOFC) through a duty cycle is calculated by finite element method (FEM) and Weibull method, respectively. Two sealing methods, namely, rigid seal and ...
Evaluation of Through-Thickness Residual Stresses by Neutron Diffraction and Finite-Element Method in Thick Weld Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-thickness distributions of the welding residual stresses were studied in the range of 50–100 mm thick plates by using finite-element modeling (FEM) and neutron diffraction measurements. In order to simulate the ...
Experimental and Numerical Study on the Reduction of Residual Stress in the Fillet Weld by Overlay Welding and Cutting Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fillet weld joint is widely used in engineering structures, but a lot of failures have been generated in the fillet joint affected greatly by weld residual stress, and it is very important to decrease the residual stress. ...
