ELASTO‐PLASTIC FINITE ELEMENT ANALYSIS OF UNILATERAL CONTACT WITH GENERALIZED COULOMB FRICTION

PHILIPPE HRYCAJ, SERGE CESCOTTO, J. OUDIN

Inside the finite element framework of LAGAMINE code, the contact conditions are introduced with specific two‐node interface elements and four‐node quadrangular elements or…

ADDING THE TIME‐DEPENDENT TERMS TO A SEGREGATED FINITE ELEMENT SOLUTION OF THE INCOMPRESSIBLE NAVIER—STOKES EQUATIONS

C.T. SHAW

To‐date, several segregated finite element algorithms have been proposed that solve the Navier—Stokes equations. These have considered only steady‐state cases. This paper…

SIMULATION OF STRAIN LOCALIZATION: A REAPPRAISAL OF THE COSSERAT CONTINUUM

RENÉ DE BORST

Classical continuum models, i.e. continuum models that do not incorporate an internal length scale, suffer from pathological mesh‐dependence when strain‐softening models are…

SIMULATION OF NON‐LINEAR VARIABLE DAMPERS USING ENERGY SIMILARITY

S. RAKHEJA, A.K.W. AHMED

A local equivalent linearization methodology is proposed to simulate non‐linear shock absorbers and dual‐phase dampers in the convenient frequency domain. The methodology based on…

ONE‐DIMENSIONAL NON‐LINEAR TRANSIENT HEAT CONDUCTION IN NUCLEAR WASTE REPOSITORIES

C.A. ESTRADA‐GASCA, M.H. COBBLE, G. ALVAREZ GARCIA

Two analytical solutions of thermal problems connected with the disposal of nuclear waste are presented. Non‐linear diffusion problems are analysed. The use of the Kirchhoff…

FINITE ELEMENT MODELLING OF THICK ISOTROPIC PLATES

SAID T. GOMAA, MOHAMMED H. BALUCH, HAMDY H. ABDEL‐RAHMAN, AMMAR K. MOHAMMED

A finite element formulation for flexure of isotropic plates based on a recent refined theory is developed. The refined theory incorporates effects of transverse shear, transverse…
