  1. Practice Problems for Axisymmetric Planar Elements Jake Blanchard Fall 2007

  2. E=100 GPa • =0.3 • Axisymmetric • Fillet radius is 5 mm • P=1 MPa • Find max Von Mises stress 4 cm 8 cm 6 cm 5 cm

  3. Spinning disk, R=15 cm • E=71 GPa • =0.33 • =2710 kg/m3 • thickness=1 cm • Spin at 1000 rpm (must enter as radians/sec) • (Load is global rotation about y axis, under inertial loads) • Both stresses are 278 kPa at center • Hoop stress is 112 kPa at edge

  4. Spinning disk with reinforcement at axle • E=100 GPa • =0.3 • =5000 kg/m3 • Spin at 10 Hz • Fillets are 1 cm radius • Find max von mises stress 2 cm 4 cm 2 cm 1 cm 12 cm
