RISA Study on the Fracture Toughness Evaluation Considering Material Tensile Characteristic for Cryogenic Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ISO 12135, a representative standard for the evaluation of fracture toughness, was revised in 2021. In the previous standard published in 2016, only yield strength was reflected for material property in fracture toughness ...
Constitutive and Fracture Modeling of Biaxially Oriented Polyethylene Terephthalate Film and Its Application to Polymer-Coated Sheet Metal Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene terephthalate (PET) films produced by rolling and tentering have biaxial orientation and thus exhibit anisotropic mechanical properties such as yielding, hardening, and fracture. The anisotropy of film makes ...
Nanocapillarity in Graphene Oxide Laminate and Its Effect on Critical Heat Flux
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nanocapillarity phenomenon involves ultralow frictional flow of water molecules through nanoscale channels, and here we study this using exceptionally large number of nanochannels within graphene oxide (GO) laminates. ...
Application of Support Vector Regression and Genetic Algorithm to Reduce Web Warping in Flexible Roll-Forming Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a flexible roll-forming process, a metal blank is incrementally deformed into the desired shape with a variable cross-sectional profile by passing the blank through a series of forming rolls. Because of the combined ...
