Non-linear buckling analysis of imperfect thin spherical pressure hull for manned submersible

Journal of Ocean Engineering and Science, 2017
Thin spherical pressure hulls are used as a human occupancy in deep water applications. DNV and other standards specify the imperfection allowed for pressure hulls.

An Analysis of elastic and inelastic lateral torsional buckling of web-tapered I beams using the finite element method

MATEC Web of Conferences, 2019
Elastic and inelastic lateral torsional buckling of simply web tapered I beam is studied using the finite element method. The length of the beams is 8000 mm for elastic lateral torsional buckling and 4000 mm for inelastic lateral torsional buckling.

Increasing the Bucking Capacity with Modal Geometric “Imperfections”

ce/papers
Abstract A recent design paradigm, named modal nudging, exploit geometric “imperfections” with negligible self‐weight change to nudge the baseline structure onto equilibrium paths of greater load‐carrying capacity. Indeed, not all imperfections are detrimental in buckling problems.

Stochastic Dynamic Buckling Analysis of Cylindrical Shell Structures Based on Isogeometric Analysis

Mathematics
In this paper, we extend our previous work on the dynamic buckling analysis of isogeometric shell structures to the stochastic situation where an isogeometric deterministic dynamic buckling analysis method is combined with spectral-based stochastic ...

Numerical Study of CFRP-Strengthened Square RC Columns under Axial Compression with Initial Geometric Imperfections

Journal of Engineering
Reinforced concrete (RC) columns are the enablers of modern cities; their numerical modeling requires precise treatment of initial geometric imperfections and confinement effects to represent their structural behavior realistically. This study describes
