OBJECTIVE To show the 12 month prevalences of mental disorders, 12-month treatment contact and use of mental health services among Cook islanders resident in New Zealand. DATA (A) The New Zealand Mental Health Survey (NZMHS) is a nationally representative face-to-face household survey, carried out in 2003-2004. It surveyed 12,992 New Zealand adults aged 16 or more including 2374 Pacflc people...

The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...

Abstract For Friction Stir Welding (FSW), several simplified FEM models have been developed to explain key parts of thermal-mechanical phenomena. In this study, simulate the FSW process AA6061-T6 aluminum alloy, a thermo-mechanical 3-D finite element model based on Coupled Eulerian-Lagrangian (CEL) approach is used. The CEL method combines benefits both Lagrangian and Eulerian approaches, allow...

On a Gleeble-3800 simulator, isothermal hot compression tests of an as-cast N06625 nickel-based alloy were conducted in wide range temperatures (950–1200 °C) and strain rates (0.1–50 s–1). Considering the influence friction adiabatic heating test, flow curves corrected. A modified Johnson-Cook, strain-compensated Arrhenius-type Hensel-Spittel constitutive models established based on corrected c...
