Summary

The paper describes a micro-method for determining the modulus of stiffness, which is the extension introduced byVan der Poel of the modulus of elasticity for visco-elastic substances, where deformation is time dependent. The procedure is based on applying a sinusoidally alternating shearing stress to the substance. The method requires at most 20 mg of material.

Zusammenfassung

Es wird eine Mikromethode zur Bestimmung des Moduls der Steifheit angegeben, die eine Weiterentwicklung der vonVan der Poel angegebenen Definition des Elastizitätsmoduls viskoelastischer Substanzen ist, bei denen die Deformation von der Zeit abhängt. Das Verfahren gründet sich auf Anwendung eines sinus-förmigen Wechselbelastung durch Scherung. Die Methode erfordert höchstens 20 mg an Untersuchungssubstanz.
