    • Buckling of nanobeams and nanorods with cracks 

      Arif, Hina; Lellep, Jaan (International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)
      Buckling of nanobeams and nanorods is treated with the help of the nonlocal theory of elasticity. The nanobeams under consideration have piecewise constant dimensions of cross sections and are weakened with cracks or ...

    • Elastic stability of uniform and hollow columns 

      Kraav, Tiina; Lellep, Jaan (Procedia Engineering, 2017)
      The stability of elastic beams and columns is investigated. The beams are subjected to the axial pressure at the elastically supported end whereas the other end of the beam is clamped. The attention is confined to the ...

    • An experimental buckling study of column-supported cylinder 

      Ozolins, Olgerts; Kalnins, Kaspars (Procedia Engineering, 2017)
      An accuracy of numerical prediction of buckling load of axially or locally loaded thin-walled circular shells was always been a challenge for engineers. With the introduction of new materials and manufacturing methods, ...

    • Experimental test for estimation of buckling load on unstiffened cylindrical shells by vibration correlation technique 

      Skukis, Eduards; Ozolins, Olgerts; Kalnins, Kaspars; Arbelo, Mariano A. (Procedia Engineering, 2017)
      Non-destructive methods to estimate the actual buckling load in particularly for imperfection sensitive thin-walled structures, are of severe interest among many fields. Particular techniques for validation of structural ...

    • Inelastic finite element analysis of lateral buckling for beam structures 

      Kala, Zdeněk; Valeš, Jan; Martinásek, Josef (Procedia Engineering, 2017)
      The inelastic lateral–torsional buckling resistance of real I-beam loaded by uniform moment was the subject of parametric studies using nonlinear finite elements, covering various initial imperfections as initial axis ...

    • Stability of von-Misses truss with initial random imperfections 

      Kala, Zdeněk (Procedia Engineering, 2017)
      The paper deals with the critical and post-critical analyses of the behaviour of a von Mises planar truss subjected to a vertical static load at its top joint. Load-deflection curves are determined using the finite element ...
