A Method for Preparing Metal Specifications for Structural Components

摘要

Specifying requirements for metallic components subject to stress and wear has long been done in most industries using the “guess and test" method. The high quality application of the guess and test method includes post test characterization of the successful component using mechanical, chemical and microstructural analysis at the very least. This paper examines a semi-quantitative design and test method that can cut months off of a traditional design sequence. Integration of semi-quantitative stress analysis and failure analysis into the design procedure allows more straightforward problem elimination, when problems arise. A few examples of how to streamline the design process for steel components is given. Much of the approach is valid for other materials, with limitations based on anisotropy, which is more pronounced in many specialty materials than in steel.
