Bending deformation capacity of large-diameter spiral-welded tubes

Vasilikis, D.; Karamanos, S. A.; Van Es, S. H. J.; Gresnigt, A. M. (2014)

Numerical simulations are conducted to define the bending deformation capacity of large-diameter spiral-welded tubes, towards efficient strain-based design. Under bending loading, the principal failure mode of those tubes ...

Buckling and classification of high-strength steel CHS tubular members under axial compression and bending

Pappa, P.; Karamanos, S. A. (2012)

EN 1993-1-1 provisions classify high-strength steel CHS members with relatively low values of D/t ratio as Class 3 or 4, so that their strength is based on elastic behavior only, neglecting their capability of sustaining ...

Buckling design of confined steel cylinders under external pressure

Vasilikis, D.; Karamanos, S. A. (2010)

Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two dimensional model with nonlinear finite elements, which accounts for ...

Elephant's foot buckling and imperfection sensitivity of internally pressurized thin-walled metal cylinders subjected to bending

Vathi M., Karamanos S.A. (2016)

Upright cylindrical steel storage tanks, subjected to lateral loading, may fail in the form of local buckling near their bottom, due to the simultaneous action of excessive axial compression in the presence of internal ...
