Modulus Of Elasticity Fatigue Strength
The modulus of elasticity of aluminum and aluminum alloys is approximately 10,300,000 lbs/sq. in. The fatigue strength of aluminum and its alloys varies from about one-quarter to one-half of the tensile strength for sections having smooth surfaces and no abrupt changes of contour. In the case of rough surfaces or irregular sections, test values obtained with smooth specimens do not necessarily apply.
Shearing Strength
Shearing strengths of aluminum alloys vary somewhat, but will average about 60% of the ultimate tensile strength.
