WebJun 20, 2024 · Using the geometric similarity of a cylindrical indentation test and the Cracked Round Bar (CRB) fracture toughness test, fracture toughness values were derived from a single indentation test by assuming that the load–depth curve of the indentation test is the same as the load–displacement curve of the CRB fracture toughness test. To ... WebISO 18489 Cracked Round Bar Test Method. In long term applications of thermoplastic materials such as polyethylene (PE) pipes or fittings it is important to rank and pre-select …
