ISO/DIS 18608-2015 pdf free.Fine ceramics (advanced ceramics, advanced technical ceramics) – Mechanical properties of ceramic composites at ambient temperature一Evaluation of the resistance to crack propagation by notch sensitivity testing. ISO/DIS 18608 describes a method for the classification of ceramic matrix composite (CMC) materials with respect to their sensitivity to crack propagation using tensile tests on notched specimens with different notch depths. Two classes of ceramic matrix composite materials can be distinguished: materials whose strength is sensitive to the presence of notches and materials whose strength is not affected. For sensitive materials, this International Standard defines a method for determining equivalent fracture toughness. The parameter, Keq, is defined as the fracture toughness of a homogeneous material which presents the same sensitivity to crack propagation as the ceramic matrix composite material which is being considered. The definition of the Keq parameter offers the possibility to compare ceramic matrix composite materials with other materials with respect to sensitivity to crack propagation.For notch insensitive materials, the concept of Keq does not apply. This International Standard applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1 D)], bidirectional (2 D)], and tridirectional (x D, where 2 <x≤3), loaded along one principal axis…
