Accuracy of methods for structural system reliability evaluation

Dan M. Frangopol, Rachid Nakib

In the last twenty years, the methods for structural system reliability evaluation have evolved considerably. Since these methods are based on different assumptions, it is…

A hierarchical structure for automatic meshing and adaptive FEM analysis

Ajay Kela, Mukul Saxena, Renato Perucchio

This paper deals initially with a new algorithm for generating automatically, from solid models of mechanical parts, finite element meshes that are organized as spatially…

CRE method of element testing and the Jacobian shape parameters

John Robinson

A general method of element testing is presented. The method applies to any shape of element with any number of nodes. The shape parameters for a quadrilateral are shown to be…

Automatic finite element modelling: geometry control for direct models

M.S. Shephard, P.L. Baehmann, K.R. Grice

The general structure of geometrically‐based automatic finite element modelling systems is discussed. The development of a specific system employing the modified‐quadtree and…

Computational techniques for the elastic—plastic analysis of tubular joints

Nelson F.F. Ebecken, Edison C.P. de Lima, Luiz Landau, Lauro H.M. Chueiri, Adilson C. Benjamin

The applicability of a non‐linear finite element method for the determination of the static strength of tubular joints is examined. In order to establish static strength…

Static analysis of contained fluids with potential‐based and displacement‐based fluid finite elements

Lorraine Olson

We compare potential‐based (ø‐U‐P0) and displacement‐based finite element methods for static analysis of contained fluids. A general transient formulation may be specialized to…

Spurious reflections and accuracy of finite element models for unbounded wave propagation problems: the one‐dimensional case

Francisco Medina, Fernando Rosales

The accuracy of finite element discretizations modelling one‐dimensional wave propagation problems is presented. The spurious reflections arising from finite/infinite element…

New triangular finite element for plates and shells

Ghazi Abu‐Farsakh

A new triangular shell finite element ‘TNTE.1’ (Ten Node Triangular Element, Model 1) is presented. The formulation is based on Sanders' theory which involves the inclusion of the…

Non‐linear analysis of symmetric structures with unsymmetric boundary conditions

Ahmed K. Noor, Sandra L. Whitworth

Two efficient computational procedures are presented for generating the global approximation vectors used in conjunction with the reduction methods for the large‐deflection…
