Vibration Analysis of an Imperfect Single-Layer Graphene Sheet using Quasi-3d Theory and Isogeometric Approach [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2023
In this study, the size-dependent free vibration analysis of a geometrically imperfect single-layer graphene sheet (SLGS) is studied by an isogeometric approach along with the quasi-3D shear and normal deformation theory.

Effect of geometric imperfections on the ultimate moment capacity of cold-formed sigma-shape se

open access: yesHBRC Journal, 2017
In recent years, cold formed steel sections are used more and more as primary framing components and as a secondary structural system. They are used as purlins and side rails or floor joist, and after that in the building envelops.

Buckling of Rectangular Plates under Nonlinear Creep

open access: yesAdvanced Engineering Research, 2023
Introduction. The task of analyzing the stability of plates and shells under creep conditions is critical for structural elements made of materials with the property of aging, which are under the action of long-term loads, since the loss of stability can
