A 12‐node hybrid stress brick element for beam/column analysis

K.Y. Sze, S.H. Lo

In this paper, a hybrid stress 12‐node brick element is presented. Its assumed stress field is derived by first examining the deformation modes of a geometrically regular element…

Computations of viscous flows using a multigrid finite volume lambda formulation

Francesco Casalini, Andrea Dadone

The viscous finite volume lambda formulation is presented. The suggested technique is apt to compute viscous flows with heat fluxes. The inviscid terms are evaluated by means of…

Non‐linear transformation of freeform curves and surfaces for CAD

Y.T. Lee, L. Fang

Non‐linear transformation of freeform curves and surfaces is useful in computer‐aided design and computer graphics. It is highly desirable that the original and transformed curves…

Fully‐developed flow and temperature calculations for rheologically complex materials using a mapped circular domain

A. Wachs, J.R. Clermont, M. Normandin

This paper considers fully‐developed flows in ducts of arbitrary shape under thermal conditions of fluids obeying various constitutive equations. The numerical method is based on…

A monomial‐based method for non‐linear structural analysis

Scott A. Burns, Keith M. Mueller

The analysis of certain structures must be performed with due consideration to non‐linear behavior, such as material and geometric non‐linearities. The existing methods for…

Layerwise adaptive topology optimization of laminate structures

W. Hansel, W. Becker

Presents a simple heuristic optimization algorithm to determine weight‐minimal laminate structures. The algorithm is based on an inverted form of growth strategy, where material…
