Introduction. Torsion test is carried out to determine the shear modulus of structural materials, such as steel and aluminum. Shear modulus is a material property that is useful in calculating the compliance of structural materials in torsion, provided that they follow Hooke’s law; that is, that the angle of twist is proportional to the applied torque. A test program of aluminum alloy solid section torsion specimens has been presented. Experimentation included tension proof tests on specimens manufactured from the purchased materials, including 6061-T6 and 5050-H32.
