RISA Tribute to Four Outstanding Associate Editors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robert G. Landers is currently a Professor of Mechanical Engineering and the Associate Chair for Graduate Affairs in the Department of Mechanical and Aerospace Engineering at the Missouri University of Science and Technology. ...
The Effect of Laser Shock Peening on Back Stress of Additively Manufactured Stainless Steel Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work studies the use of laser shock peening (LSP) to improve back stress in additively manufactured (AM) 316L parts. Unusual hardening behavior in AM metal due to tortuous microstructure and strong texture poses ...
Mitigation of Stress Corrosion Cracking in Additively Manufactured Stainless Steel by Laser Shock Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Use of laser powder bed fusion (LPBF) stainless steel in corrosive environments is attractive due to material's high corrosion resistance and fine feature resolution, which is advantageous for fluidic applications. For ...
Effect of Film Formation Method and Annealing on Morphology and Crystal Structure of Poly(L Lactic Acid) Films
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The poly(Llactic acid) (PLLA) has potential medical usage such as drug delivery since it can degrade into bioabsorbable products in physiological environments, while the degradation is affected by its crystallites. In this ...
Material Influence on Mitigation of Stress Corrosion Cracking Via Laser Shock Peening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress corrosion cracking is a phenomenon that can lead to sudden failure of metallic components. Here, we use laser shock peening (LSP) as a surface treatment for mitigation of stress corrosion cracking (SCC), and explore ...
Laser Joining of Continuous Glass Fiber Composite Preforms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A laser fusion joining method is investigated for the purpose of through thickness strengthening of glass fiber reinforced laminate composites. Laser fusion joining is evaluated as a potential process to replace mechanical ...
Laser Shock Peening for Suppression of Hydrogen-Induced Martensitic Transformation in Stress Corrosion Cracking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The combination of a susceptible material, tensile stress, and corrosive environment results in stress corrosion cracking (SCC). Laser shock peening (LSP) has previously been shown to prevent the occurrence of SCC on ...
Effect of Laser Induced Crystallinity Modification on Biodegradation Profile of Poly(L Lactic Acid)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Poly(Llactic acid) (PLLA) is of interest in drug delivery applications for its biodegradable and biocompatible properties. Polymercontrolled drug delivery relies on the release of embedded drug molecules from the polymer ...
Laser Induced Porosity and Crystallinity Modification of a Bioactive Glass Coating on Titanium Substrates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Functionally graded bioactive glass coatings on bioinert metallic substrates were produced by using continuouswave (CW) laser irradiation. The aim is to achieve strong adhesion on the substrates and high bioactivity on the ...
Removal Mechanism and Defect Characterization for Glass Side Laser Scribing of CdTe/CdS Multilayer in Solar Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser scribing is an important manufacturing process used to reduce photocurrent and resistance losses and increase solar cell efficiency through the formation of serial interconnections in largearea solar cells. Highquality ...
