Efficient handling of stability problems in shell optimization by asymmetric ‘worst-case’ shape imperfection [PDF]
, 2008 The paper presents an approach to shape optimization of proportionally loaded elastic shell structures under stability constraints. To reduce the stability-related problems, a special technique is utilized, by which the response analysis is always ...

Revista IBRACON de Estruturas e Materiais, 2018 The bare steel structural members have a low fire resistance. However, in steel and concrete composite members, the concrete encasement, besides the contribution to the stiffness of the whole system, reduces the amount of heat that reaches the steel ...

Stress-strain assessment of plain dents in gas pipelines
Fracture and Structural Integrity, 2020 Paper presents the analytical solution of the stress-strain state for a dented pipeline, based on the method of equivalent loads. First off all solution for a harmonic imperfection is found, then using Fourier series expansion a semi-analytical procedure

The effect of imperfections on crack growth rates in cold worked and interference fit holes [PDF]
Scientific Technical Review, 2019 This work examines the effect of imperfections on fatigue crack growth (FCG) in lap joints (Hi-Lok fasteners). The Finite Element Method (FEM) is used to model the cold-working and interference fit processes.

ce/papers, 2022 AbstractThe prediction of the buckling resistance of shells is subject to uncertainty since it depends significantly on the initial geometric imperfections caused by the fabrication process. However, the load case of vacuum or uniform external pressure has not yet been extensively studied.

A comparison between lift-and-project indices and imperfection ratio on web graphs
Electronic Notes in Discrete Mathematics, 2010 Abstract In this paper we study the lift-and-project polyhedral operators defined by Lovasz and Schrijver [L. Lovasz, A. Schrijver, Cones of matrices and set-functions and 0-1 optimization, SIAM J. Optimization 1, (1991), pp. 166–190] and by Balas, Ceria and Cornuejols [3] on the clique relaxation of the stable set polytope of webs.
