Question 3. A four-point bending test (Figure 3-a) was conducted to determine the properties of the beam, the cross section of which is shown in Figure 3-b. The beam is made of an elastic-plastic material for which the yield stress is 300 MPa. In the middle section of the beam, the test setup provides pure bending about the horizontal axis. Find the plastic moment Mp and the maximum elastic moment Me. Also determine the distribution of the residual stresses in the beam after the plastic moment Mois applied and then released, showing all significant values. 4-point Flexure test Force Force Loading pins a Specimen Supporting pins a: Test Setup 9 mm 150 mm N 20 mm 150 mm b: Cross Section of Beam Specimen
