【Abstract】 In this paper the critical fracture curve of mixed mode for V-notch with an interior angle α of 270° is obtained by using four-point shear specimens.The application of the maximum tensile criterion to V-notch and the size effect of the fracture criterion of mixed mode are also discussed.更多还原
