    Description / Table of Contents: Stress Intensity Factors in the Neighbourhood of a Circular Hole and their Influence on Crack Behavior.A photoelastic method was developed to determine the stress intensity factors KI and KII for cracks subjected to mixed-mode loading. The constants in the near field expansion about the crack tip were computed using a non-linear optimization program to give a best fit to the observed isochromatics. Copying the latter onto an equal density film increased their sharpness and, thus, the accuracy of the determination. The method was applied to cracks lying perpendicular to the external stress near a circular hole in a plate under uniaxial tension and the results used to describe the paths of cracks in the neighbourhood of a hole.
    Notes: Es wurden Modellexperimente durchgeführt, um den Einfluß von Inhomogenitäten - wie etwa Poren oder Einschlüsse - auf das Bruchverhalten unter statischer Belastung zu untersuchen. Änderungen der Ausbreitungsrichtung eines Risses, verursacht durch die Wechselwirkung mit einem Kreisloch in einer einachsig belasteten Platte, wurden gemessen. Zum Verständnis der beobachteten Abweichungen wurden die Spannungsfaktoren KI und KII eines Risses in der Nähe eines Kreisloches in einer Platte spannungsoptisch bestimmt. Hierzu wurden die Isochromaten um eine Rißspitze durch Verwendung eines Äquidensitenfilmes photographisch verschärft und die erhaltenen Linien durch ein nicht-lineares Optimierungsprogramm an die Nahfeld-Lösung der Spannungsverteilung um eine Rißspitze angepaßt.

    Description / Table of Contents: Concerning Investigation of Internal Electrodeposition Stress and Residual Internal Stress in Electrodeposited Nickel Coatings by Spiral Contractometer and “Strip Dilatometer” Methods.For assessing the affect of material and plating conditions on internal stress in electrodeposited coatings and its influence on material strength of plated parts it is better knowing internal stress in thin, just deposited layers (while plating process continuous) and also the course of internal stress in the coating (after plating has been finished) instead of investigating an average stress in the coating. In order to get this more substantial information on internal stresses in electrodeposited coatings a deposition model - gradual composition of the coating - and stress calculation methods were developed for Spiral Contractometer and “Strip Dilatometer”. Both methods were applied on measurements in a Watts-Nickel electrolyte.
    Notes: Für die Beurteilung werkstoff- und abscheidungsbedingter Eigenspannungszustände in galvanischen Schichten und ihres Einflusses auf Festigkeitseigenschaften beschichteter Bauteile ist es vorteilhaft, statt der mittleren Schichteigenspannungen erstens kontinuierlich über dem Schichtwachstum die Eigenspannungen dünner Schichtinkremente zu ermitteln und zweitens den Verlauf der - nach beendeter Abscheidung - tatsächlich über der Schichtdicke wirkenden Eigenspannungen zu bestimmen. Um diese differenzierte Aussage über Eigenspannungen in galvanischen Schichten zu erhalten, wurden anhand eines Abscheidungsmodells - schrittweiser Aufbau der Schicht - Rechenverfahren für Messungen mit dem Spiralkontraktometer und dem Streifendehnungsmeßgerät entwickelt und an Nickelschichten aus dem Watts-Bad praktisch erprobt.
