Decomposition of the initial stability problem for a cylindrical shell under non‐symmetric loads

Krzysztof Wiśniewski, Robert L. Taylor

Numerical aspects of initial stability analysis of a cylindrical shell of non‐constant parameters along the generator and under non‐symmetrical loads are considered. A variational…

Efficient partitioning schemes for fluid‐structure interaction problems

R.K. Singh, T. Kant, A. Kakodkar

This paper demonstrates the capability of staggered solution procedure for coupled fluid‐structure interaction problems. Three possible computational paths for coupled problems…

Automatic crack propagation studies in T‐junctions and cross bars

E.M. Remzi, W.S. Blackburn

Theoretical investigations have been performed on slowly propagating cracks in T‐junctions and cross bars using computer procedures developed to analyse the amount and direction…

Computation of bending disturbances in axisymmetrically loaded spherical shells: a study of the accuracy of Geckeler's approximation

Alphose Zingoni, Milija N. Pavlović

The accuracy of the bending disturbances in (axisymmetrically loaded) spherical shells is computed by means of the widely used simplified method known as Geckeler's approximation…

Finite element model for the analysis of a building

A. Bouberguig

Many problems are identified in the static analysis of a building based on ‘slabs, walls, columns’ by the classical method consisting of isolating the corresponding slab at each…

Analysis of three‐dimensional prestressed concrete structures using a non‐linear material model

C. Majorana, A. Natali, R. Vitaliani

The aim of the present work is to describe a numerical approach to the analysis of three‐dimensional reinforced concrete structures subject to prestressing. The finite element…

Finite strip method for groundwater modelling in a parallel computing environment

J.A. Puckett, R.J. Schmidt

The finite strip method has been shown to apply to many problems in continuum mechanics. Within the constraints of the method, it has been shown to be superior to the finite…

Programming the isoparametric six‐node triangle

Carlos A. Felippa

The formulation and programming of the six‐node, curved isoparametric triangle in plane stress is presented. This is intended to fill an apparent vacuum in the open finite element…
