Nonlinear Dynamics of Imperfect FGM Conical Panel
Shock and Vibration, 2018 Structures composed of functionally graded materials (FGM) can satisfy many rigorous requisitions in engineering application. In this paper, the nonlinear dynamics of a simply supported FGM conical panel with different forms of initial imperfections are ...

Interactive Buckling of Q420 Welded Circular Tubes under Axial Compression
Advances in Materials Science and Engineering, 2020 Finite element models (FE models) of high-strength steel Q420 (yield strength 420 MPa) circular tubes considering residual stresses and local and overall geometric imperfections were established and verified against existing test data. Based on parameter

Fourier representation of geometrical imperfection for probabilistic buckling analysis
Jurnal Ilmiah SINERGIThis research studies the first part of the failure of a compression member structure due to buckling. This unstable equilibrium collapse, exposes brittle failure which occurs suddenly and therefore should be avoided wherever possible.

Numerical Analysis Of Buckling Of Von Mises Planar Truss
Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2015 A computational algorithm of a discrete model of von Mises planar steel truss is presented. The structure deformation is evaluated by seeking the minimal potential energy. The critical force invented by mathematical solution was compared with solution by

Shape and Size of Initial Geometrical Imperfections of Structural Glass Members
Transactions of the VŠB – Technical University of Ostrava, Civil Engineering Series., 2017 Abstract In this paper measuring and determining of initial geometrical imperfections of set of glass members are presented. Measured specimens had the different dimensions and different composition – monolithic glass or laminated glass using different types of interlayer foils and glass panes.
