Abstract

Palmqvist crack extension in WC‐Co can be described using the center‐loaded penny crack analogy. When Palmqvist cracks are represented by semicircles of diameter l (l=crack length measured from an impression corner), the stress intensity factor which controls crack extension differs from that of a half‐penny crack of radius l+a (2a = impression size) by only a slowly varying factor m=21/2 (l/a)1/2; m≅1.0 to 2.4 for WC‐Co and m≅0.8 to 1.4 for ceramics.
