Описание: Shot peening is a complex cold working process commonly used to improve the fatigue life of critical components. The process involves a large number of spherical beads (with diameters in the order of a few mm) impacting surfaces at high speeds. The Almen intensity is one of the main parameters used to quantify the intensity of a shot peeing process. It is related to the amount of energy transfer from shot stream to the workpiece . Almen intensity is measured indirectly by shot peening a thin rectangular strip, also known as Almen strip, which is fixed onto a holder by using four bolts. When the bolts are removed, the stresses in the strip readjust leading to a bow in the direction of peeing.
