نویسندگان
چکیده
The in-plane elastoplastic failure mechanism of plate-tube-connected steel circular arches with inverted triangular cross sections is investigated in this study by using theoretical derivation and numerical simulation. First, the elastic buckling load formula arch under full-span uniform radial (FSURL) presented. Then, limited conditions avoiding connecting plate chord local before global instability are derived. Lastly, elastic–plastic mechanisms studied FSURL, vertical (FSUVL), half-span (HSUVL). It found that will experience failure, combined FSUVL HSUVL. mode mainly related to stiffness plate. corresponding design formulas proposed for chord. FE results good agreement.

متن کاملFailure of high strength steel sheets: Experiments and modelling
Failure in sheet metal structures of ductile material is usually caused by one of, or a combination of, ductile fracture, shear fracture or localised instability. In this paper the failure of the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M is explored. The constitutive model used in this study includes plastic anisotropy and mixed isotropic-kinematic hardening....
