26 - Determination of Poisson's Ratio in ADI

Abstract:

With the emerging computer technology in recent years, design criteria and techniques have changed. One of the new and widely accepted methods is the finite element design. The Poisson's ratio is part of the finite element calculations and its importance in design has increased recently. Concurrently with the development of the computer technology, austempered ductile iron, ADI, has emerged as a new engineering material. AD1 was successful in many applications in every segment of the industry. The Poisson's ratio has become a necessary but unavailable design property in ADI. Without the knowledge of the Poisson's ratio, the modern methods may not be used in designing AD1 components.
