Rock mechanics Aims and scope Submit manuscript

Summary

This paper presents an experimental study of the newly developed double-punch test method for determination of the tensile strength of rocks. The method for preparation of test specimens and test procedure is reported and discussed. Comparisons of tensile strength determined from double-punch and split-cylinder tests are also presented.

Zusammenfassung

Ein neu entwickeltes „double-punch“-Verfahren für die Bestimmung der Zugfestigkeit von Gesteinen wird beschrieben. Die Vorbereitung der Versuchsobjekte und die Durchführung der Versuche werden erläutert. Außerdem werden die Zugfestigkeiten nach dem „double-punch“- und „split-cylinder“-Verfahren verglichen.

Résumé

Dans cet article une nouvelle méthode de double poinçonnement permettant de déterminer la résistance à la traction des roches est présentée. La préparation des éprouvettes ainsi que la méthode d'essai sont décrites. Une comparaison est faite entre la résistance à la traction obtenue par double poinçonnement et par fendage d'un dylindre (compression diamétrale).
