FUNDAMENTAL ISSUES IN FINITE ELEMENT ANALYSES OF LOCALIZATION OF DEFORMATION

R. DE BORST, L.J. SLUYS, H.‐B. MUHLHAUS, J. PAMIN

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

MULTIGRID TECHNIQUE FOR THE COMPRESSIBLE EULER AND NAVIER‐STOKES EQUATIONS

A.E. KANARACHOS, I.P. VOURNAS

An optimized multigrid method (NSFLEX‐MG) for the NSFLEX‐code (Navier‐Stokes solver using characteristic flux extrapolation) of MBB (Messerschmitt Bolkow Blohm GmbH) is described…

STRUCTURAL SHAPE OPTIMIZATION OF VIBRATING SHELLS AND FOLDED PLATES USING TWO‐NODED FINITE STRIPS

E. HINTON, M. ÖZAKÇA, N.V.R. RAO

This paper deals with structural shape optimization of vibrating prismatic shells and folded plates. The finite strip method is used to determine the natural frequencies and modal…

PSEUDO‐TRANSIENT LARGE‐DEFLECTION ELASTIC ANALYSIS OF FIBRE REINFORCED COMPOSITE PLATES

T. KANT, J.R. KOMMINENI

A unified approach is presented for the pseudo‐transient (static) linear and geometrically non‐linear analyses of composite laminates. A finite element idealization with a…

SENSITIVITY STUDY OF CRITERIA GOVERNING COLLAPSE OF CENTRALLY LOADED R/C SLABS

M.S.A. ABBASI, M.H. BALUCH, A.K. AZAD, H.H. ABDEL‐RAHMAN

This paper presents the full range sensitivity study of various components of material model on the response of reinforced concrete slabs subjected to central patch loads using…
