Expert systems for finite element analysis and design optimization—a review

J. Mackerle, K. Orsborn

Expert systems technology as an area of artificial intelligence is coming to the field of structural mechanics. A number of expert systems have been developed or are under…

A simple method for the calculation of postcritical branches

W. Wagner, P. Wriggers

The practical behaviour of problems exhibiting bifurcation with secondary branches cannot be studied in general by using standard path‐following methods such as arc‐length…

An isoparametric eccentrically stiffened plate bending element

P.A. Thompson, P. Bettess, J.B. Caldwell

An 8 noded, eccentrically stiffened, plate bending element is introduced. The formulation allows for any number of stiffeners arbitrarily orientated within a plate element without…

Hybrid transfinite element modelling/analysis of non‐linear heat conduction problems involving phase change

Kumar K. Tamma, Sudhir B. Railkar

The present paper describes the applicability of hybrid transfinite element modelling/analysis formulations for non‐linear heat conduction problems involving phase change. The…

Partitioned analysis for coupled mechanical systems

Carlos A. Felippa, Thomas L. Geers

Partitioned analysis is a method by which sets of time‐dependent ordinary differential equations for coupled systems may be numerically integrated in tandem, thereby avoiding…

An implicit implementation of harmonic balance method for non‐linear dynamic systems

Y.K. Cheung, V.P. Iu

A simple numerical algorithm is developed for the implementation of the harmonic balance method to analyse periodic responses of a general dynamic system having geometrical…

Comparison of various models for strain‐softening

Gilles Pijaudier‐Cabot, Zdeněk P. Bažant, Mazen Tabbara

This paper presents a comparison of various models for strain‐softening due to damage such as cracking or void growth, as proposed recently in the literature. Continuum‐based…

Simulation of hot flat rolling of steel by the finite element method

N. Kapaj, E. Amici, S. Ghini, C. Pietrosanti

This paper presents a finite element simulation of the hot fiat rolling of steel. An elastoplastic behaviour of steel and plane strain are assumed. The results presented here were…

Free vibration analysis of plates, bridges and axisymmetric shells using a thick finite strip method

B. Suárez, J. Miquel Canet, E. Oñate

A unified approach for the vibration analysis of curved or straight prismatic plates and bridges and axisymmetric shells using a finite strip method based in Reissner—Mindlin…

Solution of incompressible steady flow problems in closed conduits using finite elements and a structural analogy

Arturo O. Cifuentes

A problem that arises very frequently in many industrial applications is the study of steady incompressible flows in a network of pipes. This paper introduces a structural analogy…
