RISBuckling of Plates with Arbitrary Geometric Configurations via the Discrete Ritz Method
Publisher: American Society of Civil Engineers
Abstract: A discrete Ritz method (DRM) is presented for buckling analysis of plates with arbitrary geometric configurations employing the concept of representing structural energy with global variable stiffness. In the DRM approach, ...
A Simplified Strategy to Address Effects of the Drop of Temperature on the Gurson-Tvergaard-Needleman Model for G20Mn5QT Cast Steels
Publisher: ASCE
Abstract: G20Mn5QT cast steels have been widely used in cast steel connections, which may suffer from ductile fracture at ambient temperature. Northern climates make the problem even worse because the ductility of the cast steels ...
Material Parameters in the GTN Model for Ductile Fracture Simulation of G20Mn5QT Cast Steels
Publisher: ASCE
Abstract: Material parameters in the Gurson, Tvergaard and Needleman (GTN) model were calibrated for G20Mn5QT cast steels based on tests of tension coupons and smooth notched tensile specimens, and complementary FEA. The mesh ...
