| Abstract: | In this paper, the practical test method for determining fracture toughness of ductile materials are recommended in order that the fracture test can be universally applied to examine and determine material be-haviours. This type of method and technique consist of side-cut three-point bend specimen, two-point displacement method for measuring (?) and displacement-gauge method for measuring J u . These methods and techniques can be used easily and economically to produce accurate results. |
