Webmaximum stress σ max Stress ratio A = alternating stress= σ a mean stress σ m Static Stress When a part is subjected to a load that is applied slowly, without shock, and is held at a constant value, the resulting stress in the part is called static stress. Because σ max = σ min, the stress ratio for static stress is R = 1.0. WebExample of Thermal stress. The gap between the inner and outer end of the rail track is an excellent example of a rail track. The two steel rods we use as rails on which the train passes. These steel rods are in touch with outer and inner ends. The extent of thermal stress produced due to temperature and friction can easily bend these rods.
