FINITE ELEMENT STRUCTURAL SHAPE AND THICKNESS OPTIMIZATION OF AXISYMMETRIC SHELLS

E. HINTON, N.V.R. RAO, J. SIENZ

This paper deals with structural shape and thickness optimization of axisymmetric shell structures loaded symmetrically. In the finite element stress analysis use is made of newly…

COMPUTER SIMULATION OF THREE‐DIMENSIONAL CONVECTION IN TRAVELLING MIG WELD POOLS

CHUAN SONG WU

Mathematical models of the metal‐inert gas (MIG) welding process may be used to study the influence of various welding parameters on weld dimensions, to assist in the development…

MULTIOBJECTIVE DESIGN OPTIMIZATION OF CONTINUOUS BEAMS BY NUMERICAL METHODS

SRINIVAS KODIYALAM, S. ADALI, I.S. SADEK

The optimal thickness distribution of a two‐span continuous beam is determined with the objectives of minimizing the maximum stress, maximizing the fundamental frequency and…

USING PSEUDO‐CONCENTRATIONS IN THE ANALYSIS OF TRANSIENT FORMING PROCESSES

H.J. ANTÚNEZ, S.R. IDELSOHN

The pseudo‐concentration method is applied to the analysis of transient processes. A simple, easy‐to‐handle model is obtained by keeping an Eulerian description: it does not…

COMPUTATION AND ANALYSIS OF MULTI‐EXCITATION RANDOM SEISMIC RESPONSES

LIN JIAHAO, F.W. WILLIAMS

Because of the extensive use of long‐span structures in modern engineering, much attention has been given to the extent to which ground motion phase‐lags affect the internal…

SIMULATION OF INDUSTRIAL FORGING OF AXISYMMETRICAL PARTS

K. HANS RAJ, L. FOURMENT, T. COUPEZ, J.L. CHENOT

Numerical modelling and simulation of metal forming is rapidly gaining prominence in many industries all over the world due to its effective saving of production time, effort and…
