Influence of Initial Imperfections on the Laterally Loaded Cylindrical Shell [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The article deals with the assessment of influence of initial imperfection on the loss of stability of laterally loaded cylindrical shell. The studied structure is a simplified case of the horizontal cylindrical shell (road tank [1, 2]) located on saddle

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections
Applied Sciences, 2022 In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,

Stability Analysis of Nonlocal Elastic Columns with Initial Imperfection [PDF]
Mathematical Problems in Engineering, 2013 Investigated herein is the postbuckling behavior of an initially imperfect nonlocal elastic column, which is simply supported at one end and subjected to an axial force at the other movable end. The governing nonlinear differential equation of the axially loaded nonlocal elastic column experiencing large deflection is first established within the ...

CD271 is an imperfect marker for melanoma initiating cells
Oncotarget, 2014 Understanding the molecular and cellular processes underlying melanoma plasticity and heterogeneity is of paramount importance to improve the efficiency of current treatment and to overcome resistance to chemotherapy drugs. The notion of plasticity and heterogeneity implies the existence of melanoma cell populations with different phenotypic and ...

Effect of Residual Stresses on the Elastoplastic Behavior of Welded Steel Plates
Journal of Marine Science and Engineering, 2020 A robust methodology to simulate virtually the residual stresses pattern in welded steel plates is presented. The methodology is applied to the structural analysis of typical welded plates belonging to ship structures, and the effect of residual stresses
