Cylinder thermal expansion
WebWhen a press or shrink fit is used between 2 cylinders of the same material, an interface pressure p i is developed at the junction of the cylinders. If this pressure is calculated, the stresses in the cylinders can be found using the above equations. The pressure is: Where: E = Young’s Modulus δ= radial interference between the two cylinders WebIn the contraction of a hot steel cylinder immersed in a cooler medium, the coefficient of thermal expansion of steel decreases with temperature. Assuming that the coefficient of thermal expansion is constant can …
