RISA State-of-the-Art Review on Hemming: A Materials Processing Technology for Mechanical Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hemming is a material processing technology widely used in major sectors such as automotive and aerospace industries. As a mechanical joining process, hemming is applied to sheet metal components to build structural ...
Model Development of Torsional Drillstring and Investigating Parametrically the Stick Slips Influencing Factors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drillstring vibration is one of the limiting factors maximizing drilling performance. Torsional vibrations/oscillations while drilling is one of the sever types of drillstring vibration which deteriorates the overall ...
Compression of Fibrous Assemblies: Revisiting the Stress–Density Relation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many engineering materials are made from fibers, and fibrous assemblies are often compacted during the fabrication process. Compression leads to the formation of contacts between fibers, and this causes stiffening. The ...

Environmental Fatigue and Static Behavior of RC Beams Strengthened with Carbon-Fiber-Reinforced Polymer
Publisher: American Society of Civil Engineers
Abstract: Many countries around the world have tremendous needs to repair and strengthen their transportation infrastructure. Almost everywhere, traffic loads have reached levels largely exceeding design expectations. Northern ...
Soot Evolution With Cyclic Crank-Angle-Resolved Two-Color Thermometry in an Optical Diesel Engine Fueled With Biodiesel Blend and ULSD
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biodiesel is a desirable alternative fuel for the diesel engine due to its low engine-out soot emission tendency. When blended with petroleum-based diesel fuels, soot emissions generally decrease ...
Investigations on Oilwell Cement Strength Response to Ultrasonic Measurements in the Presence of Additives1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Well cements are an important aspect of wellbore integrity and recent investigations focus on describing the cement lifetime using, when possible, nondestructive tests like ultrasonic measurements. However, the original ...
3D Printing of Flexible and Stretchable Parts Using Multiwall Carbon Nanotube/Polyester-Based Thermoplastic Polyurethane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports on the 3D printing of flexible and stretchable parts based on multiwall carbon nanotube (MWCNT)/polyester-based thermoplastic polyurethane (TPU) nanocomposites. The rheological properties of the WCNT/TPU ...
CFRP Prestressed High-Strength Concrete Prisms Subjected to Direct Tension
Publisher: American Society of Civil Engineers
Abstract: This paper describes the behavior of carbon fiber-reinforced polymer (CFRP) prestressed high-strength concrete prisms under direct tension. Seven prestressed concrete prisms with different levels of prestressing were cast ...
Effect of Reprocessing on the Rheological, Electrical, and Mechanical Properties of Polypropylene/Carbon Nanotube Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, polypropylene (PP) filled with different levels of multiwalled carbon nanotubes (MWCNTs) manufactured by injection molding was closed-loop recycled in order to investigate the effect of recycling and ...
