The brittle fracture in the torsion test results in ________ geometry.

The brittle fracture in the torsion test results in ________ geometry. Correct Answer helical shape

The brittle material in the plane is perpendicular to the direction of the maximum tensile stress. This plane bisects the angle between the two planes of the maximum shear stress and makes an angle of 45o with longitudinal and transverse directions; it results in the helical fracture.
