Abstract

A new method for the interpolation of biaxial anisotropy of elastic modulus of thin-plate polycrystalline elements has been developed. The dependence of shear modulus and modulus of longitudinal elasticity as a function of an angular distribution of Poisson's ratio, achieved by the method of ultrasonic critical-angle refractometry (UCR), has been derived.

Kurzfassung

Es wurde ein neues Verfahren für die Interpolation der biaxialen Anisotropie des Elastizitätsmoduls von dünnplattigen polykristallinen Elementen entwickelt. Die Abhängigkeit des Schermoduls und des Elastizitätsmoduls in Längsrichtung wurde als Funktion der Winkelverteilung der Poisson-Zahl abgeleitet und mit dem Verfahren der Winkel-Ultraschallrefraktometrie (ultrasonic critical-angle refractometry (UCR)) bestimmt.
