The possibility of determining the fracture toughness under conditions of elastic contact during dynamic indentation is analyzed. Procedures are proposed for estimating the critical stress intensity factor from the parameters of initiating cracks and directly from the contact force versus indentation depth curve during dynamic indentation.
