RISOn Serrated Plastic Flow in an AA5052-H32 Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Temporal and spatial characteristics of serrated plastic flow or the so-called Portevin-Le Chatelier (PLC) deformation bands in a commercial Al-2.5%Mg sheet metal due to dynamic strain aging ...
Modeling the Rotation of Orthotropic Axes of Sheet Metals Subjected to Off-Axis Uniaxial Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified version of a newly developed anisotropic plasticity theory is presented to describe the anisotropic flow behavior of orthotropic polycrystalline sheet metals under uniaxial tension. ...
Setting Maximum Incentive for Incentive/Disincentive Contracts for Highway Projects
Publisher: American Society of Civil Engineers
Abstract: An increasing number of State Highway Agencies (SHAs) are utilizing Incentive/Disincentive (I/D) bidding for highway construction. The I/D bidding concept is designed to shorten the total contract time by giving the ...
Time Is Money: Innovative Contracting Methods in Highway Construction
Publisher: American Society of Civil Engineers
Abstract: In today's highway construction industry, the focus has shifted from building new transportation facilities to resurfacing, rehabilitating and restoring (3R's) those already in existence. These types of projects create a ...
Strain Accumulation in Polymer Electrolyte Membrane and Membrane Electrode Assembly Materials During a Single Hydration/Dehydration Cycle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A digital image correlation technique was used to measure drying-induced strains in perfluorosulfonic acid (PFSA) membrane and membrane electrode assembly (MEA) materials which are key components ...
