RISIdeal Flow in Plasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ideal plastic flows constitute a class of solutions in the classical theory of plasticity based on, especially for bulk forming cases, Tresca’s yield criterion without hardening and its associated ...
Semi-Analytic Hybrid Method to Predict Springback in the 2D Draw Bend Test
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified numerical procedure to predict springback in a 2D draw bend test was developed based on the hybrid method which superposes bending effects onto membrane solutions. In particular, ...
Improvement of Formability and Spring-Back of AA5052-H32 Sheets Based on Surface Friction Stir Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A process to improve formability and spring-back was developed for AA5xxx-H temper sheets based on the surface friction stir (SFS) method. In the SFS method, a rotating probe stirs the sheet ...
Incorporation of Sheet-Forming Effects in Crash Simulations Using Ideal Forming Theory and Hybrid Membrane and Shell Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to achieve reliable but cost-effective crash simulations of stamped parts, sheet-forming process effects were incorporated in simulations using the ideal forming theory mixed with the ...
