INTRODUCTION The WHO Safer Surgery checklist has become an important component of perioperative safety. Our objective, was to determine the compliance of completing the checklist for paediatric emergency plastic surgery patients at our unit. METHODS An initial baseline was performed with 70 patients over two months at our unit. Following this, we raised awareness at an audit meeting and close...

Variable cross-section roll forming is a new process developed on the basis of traditional constant forming. It can produce variable products flexibly and efficiently, which great significance to automobile lightweight. In this paper, rolling section longitudinal beam simulated, finite element model sheet metal established in ABAQUS software, deformation stress distribution are analyzed. conclu...

the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

The surface quality of an aluminum foam sandwich panel (AFSP) is very important for its appearance and application. This paper mainly studies the AFSP after plastic forming. Combined with three-dimensional (3D) scanning technology, normal deviation between experimental target was obtained, parameters Sq, Sz dmax were calculated to evaluate quality. models cubic-spherical (CS) tetrakaidecahedral...

A new method has been proposed in this study for the elastic-plastic buckling analysis of stiffened panels under global bending. In method, a simplified model built with application two theories plasticity, incremental theory (IT) and deformation (DT). The effect transverse shear through stiffener thickness considered using Mindlin-Reissner plate theory. governing differential equations have so...
