Description

The finite element method is utilized to calculate the calibration curves, which are required for the electrical direct-current potential crack-monitoring systems as applied to fracture mechanics specimens with the thickness of 5 mm, 10 mm, 15 mm, 18 mm and 20 mm. The starting crack is asub(o) = 2 mm for all specimens. (orig.)

Abstract (German)

Mittels der Finite-Element-Methode werden die Eichkurven berechnet, die zur Anwendung der elektrischen Gleichstrom-Potential-Methode fuer die Messung der Risstiefe von Oberflaechenrissen in Bruchmechanikproben benoetigt werden. Die Eichkurven werden fuer Proben mit den Dicken von 5 mm, 10 mm, 15 mm, 18 mm und 20 mm ermittelt. Die Anrisstiefe ist fuer alle Proben asub(o) = 2 mm. (orig.)
