This work investigated buckling resistance of an X80 steel pipe containing a corrosion defect
under axial compressive loading by finite element analysis. A 3-dimensional numerical …

A novel methodology for imperfection sensitivity analysis is presented. Koiter׳ s perturbation
method is used to calculate the imperfection paths emanating from mode interaction …

A mixed formulation, four node, flat shell element is proposed for the geometrically nonlinear
analysis of laminated composite plates. The element is based on the linear analysis of …

A principal issue in any co‐rotational approach for large displacement analysis of plates and
shells is associated with the specific choice of the local reference system in relation to the …

Accurate prediction of tensile strain capacity (TSC) is the key to the strain-based design and
assessment (SBDA) of buried pipelines. Various TSC prediction models proposed by …

A nine‐node corotational curved quadrilateral shell element with novel treatment for rotation
at intersection of folded and multishell structures is presented. The element's corotational …

In this work, a simple but robust 8-node 16-DOF quadrilateral membrane element with
exceptional tolerances to mesh distortion is proposed for efficiently analyzing the two …

This paper presents a simplified co‐rotational formulation for quadrilateral shell elements
inheriting the merit of element‐independence from the traditional co‐rotational approach in …

In this paper, a novel co-rotational framework for quadrilateral shell element allowing for the
warping effect based on the pure deformational method is proposed for geometrically …

Within the framework of six-parameter non-linear shell theory, with strain measures of the
Cosserat type, we develop small-strain J 2-type elastoplastic constitutive relations. The …
