Tolerance Analysis for Sheet Metal Assemblies
Traditional tolerance analyses such as the worst case methods and the statistical methods are applicable to rigid body assemblies. However, for flexible sheet metal assemblies, the traditionalExpand
3-Methoxysampangine, a novel antifungal copyrine alkaloid from Cleistopholis patens.
Further examination of the active ethanolic extract of the root bark of Cleistopholis patens by using bioassay-directed fractionation resulted in the isolation of a new alkaloid, 3-methoxysampangineExpand
A parametric study of joint performance in sheet metal assembly
In sheet metal assembly, joints are designed to facilitate welding the parts and to form various shapes and dimensions of sheet metal products. The most commonly used joints are lap joints, buttExpand
An offset finite element model and its applications in predicting sheet metal assembly variation
Dimensional variation in sheet metal assembly affects product fit and functionality. To predict the variation of assembled products, variation simulation analysis has been gradually adopted in theExpand
