Abstract:
An effective approximate method is proposed to obtain the stress intensity factors (SIF) of the chevron notched three-point bend round bar specimens, the least square principle is applied to fit the results into a polynomial for SIF,which is applied to the fracture toughness specimen suggested by the International Society for Rock Mechanics(ISRM) ,the result is satisfatory.
