摘要：本文介绍注塑模具设计生产翘曲测试样本以及为了获得残余热应力的影响,在模具中执行热分析。这项技术、理论、方法在注射模具设计中必须被考虑运用。 在商业计算机上使用...

摘要对于模制件，包括产品模型的侧凹特征和自由曲面，提出一种自动确定分型线的新方法。这个简短的过程包括：1）通过识别侧凹特征和应用有限元的方法将产品实体模型转换成离散...

ABSTRACT This paper describes analytical structural models created for various components of the Tobin Memorial Bridge, and a program of instrumentation and non-destructive testing for the Little Mystic Span. A detailed global finite element...

Abstract In progressive dies, two or more stations are usedto produce sheet metal components. In each station, one ormore processes are applied. The progressive dies reduce thetime and cost of producing complex sheet metal com-ponents. Howev...

Structural Systems to resist lateral loads Commonly Used structural Systems With loads measured in tens of thousands kips, there is little room in the design of high-rise buildings for excessively complex thoughts. Indeed, the better high-r...

AbstractIn this study, an experimental test on a full-scale model of a two-span continuous composite two-girder bridge with prefabricated slabs wascautiously conducted and observed in order to study crack control. In the testing, a first lo...

This paper presents a practical prototype knowledge-basedsystem, called IKMOULD, for mould design in the injectionmoulding process. It attempts to tackle the problem in apractical and integrative way, unlike the stand-alone andmathematical p...

A multi-step unfolding method (MSUM) is developed for blank design and formability pre-diction of complicated progressive die stamping part. In themethod, a finite elementmodelof the inverse approach (IA) is developed at a local area accord...
