    • Buckling of unconfined and confined thin-walled steel cylinders under external pressure 

      Vasilikis, D.; Karamanos, S. A. (2008)
      The present paper investigates the structural stability of thin-walled steel cylinders subjected to uniform external pressure. A brief discussion of unconfined steel cylinder buckling is presented first. Subsequently, ...

    • Buried steel pipelines crossing strike-slip faults 

      Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (2012)
      The paper examines the behaviour of buried steel pipelines crossing active strike-slip faults. The vertical fault plane is crossed by the pipeline at an angle ranging between zero and 45 degrees, causing significant plastic ...

    • Finite element analysis of buried steel pipelines under strike-slip fault displacements 

      Vazouras, P.; A.karamanos, S.; Dakoulas, P. (2011)
      The present paper investigates the mechanical behavior of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and crosses the pipeline axis at a certain angle. The interacting ...

    • Local buckling strength and deformation capacity of pipes 

      Gresnigt, A. M.; Karamanos, S. A. (2009)
      Local buckling in cylindrical shells may occur elastically or plastically, mainly depending on the diameter to wall thickness ratio. In offshore structures plastic local buckling is mostly the governing criterion. In thin ...

    • Pipe-soil interaction and pipeline performance under strike-slip fault movements 

      Vazouras, P.; Dakoulas, P.; Karamanos, S. A. (2015)
      The performance of pipelines subjected to permanent strike-slip fault movement is investigated by combining detailed numerical simulations and closed-form solutions. First a closed-form solution for the force-displacement ...

    • Stability of confined thin-walled steel cylinders under external pressure 

      Vasilikis, D.; Karamanos, S. A. (2009)
      The present paper investigates the structural stability of thin-walled steel cylinders surrounded by an elastic medium, subjected to uniform external pressure. A two-dimensional model is developed, assuming no variation ...

    • Steel elbow response under strong cyclic loading 

      Varelis, G. E.; Gresnigt, A. M.; Karamanos, S. A. (2012)
      The present study examines the behavior of steel pipeline elbows subjected to strong cyclic loading conditions. A set of experiments is conducted where in-plane cyclic bending with constant amplitude is applied on the elbow ...
