Finite element simulation of the inertia welding of two similar parts

A. Moal, E. Massoni

A complete thermo‐mechanical model for the simulation of theinertia welding process of two similar parts is described. The materialbehaviour is represented by an incompressible…

High order gradient smoothing towards improved C1 eigenvalues

Jacob Avrashi

This article deals with improvement of eigenvalues obtained by finiteelement analysis of C¹ eigenproblems. The proposed method employshigh order gradient smoothing at nodal points…

Computations of aerodynamic drag for spinning transonic projectiles using an implicit TVD scheme

Jan‐Kaung Fu

The performance of a spinningsecant‐ogive‐cylinder‐boattail projectile in thetransonic regime in terms of aerodynamic drag has been analyzed numericallyin this study. To obtain an…

Adaptive quadtree subdividing contour plotting algorithms

K.P. Wang, J.C. Bruch

Two simple and efficient contour plotting algorithms are presented. Thefirst algorithm is a colour‐fill algorithm. The second algorithm is acolour‐fill algorithm as well as a…

Comparison of two higher order finite element models for composite materials and experimental validation

A. Tchiftchibachian

Two displacement‐based higher‐order models are analysed.The in‐plane displacements are a cubic variation of the thicknesscoordinate for the first model. The other cubic model is…

Finite element analysis of Saint‐Venant end effects in micropolar elastic solids

S. Nakamura, R.S. Lakes

Distributions of stress and strain in composite and cellular materialscan differ significantly from the predictions of classical elasticity. Forexample, concentration of stress…
