    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 15.01, 2018 Describes the fracture toughness, K[Ic], determination of advanced ceramics at ambient temperature.

    Scope - (Show below) - (Hide below)

    1.1These test methods cover the fracture toughness, KIc, determination of advanced ceramics at ambient temperature. The methods determine KIpb (precracked beam test specimen), KIsc (surface crack in flexure), and KIvb (chevron-notched beam test specimen). The fracture toughness values are determined using beam test specimens with a sharp crack. The crack is either a straight-through crack formed via bridge flexure (pb), or a semi-elliptical surface crack formed via Knoop indentation (sc), or it is formed and propagated in a chevron notch (vb), as shown in Fig. 1.

    1.6Values expressed in these test methods are in accordance with the International System of Units (SI) and IEEE/ASTM SI 10.

    1.7The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
