0/ During the rolling process, the average flow stress is 20,000 lb/in², etermining the amount of reduction in the cross-sectional area (use n = 0.40 and K = 35,000 lb/in²).
In a tensile test on a steel tube of external diameter 18 mm and internal diameter 12 mm, an axial pull of 2 kN produces stretch of 6.72x 10^-3 mm in a length of 100 mm and a lateral contraction of 3.62x10^-4mm in outer diameter. Calculate the values of three modulus and Poisson's ratio of the material
An indirect extrusion operation produces the cross-section shown in Figure 1 (Dimensions in cm) from an aluminum alloy (annealed) billet whose diameter is 300 mm and length of 500 mm. In the Johnson strain equation, a=0.8 and b=1.2 1.1 calculate shape factor of the product 1.2 If the butt left in the container at the end of the stroke is 25 mm thick, what is the (5)length of the extruded section?
A direct extrusion operation the cross section shown in Figure is produced from a copper billet whose diameter 225mm and length = 500 mm. In the flow curve for copper, the strength coefficient = 400 MPa and strain hardening exponent = 0.30. In the Johnson strain equation, a = 0.8 and b = 1.5. Determine: 1. The extrusion ratio, 2. The shape factor, 3. The force required to drive the ram forward during extrusion at the point in the process when the billet length remaining in the container = 325 mm ,4.The length of the extruded section at the end of the operation if the volume of the butt left in the container is 225,000 mm3. * 100
A compound cylinder is formed by shrinking one cylinder over another, the final dimensions being, inner diameter = 150mm, diameter at the junction = 200mm, outer diameter = 250mm. If the radial pressure at the junction due to shrinkage is 40N/mm2, calculate: (a) Initial stresses in the cross section of the tube. (b) If a fluid pressure of 80N/mm2is admitted in the compound tube calculate the final stresses. Plot the variation of hoop and radial stress across the wall thickness.
