  1. Evaluation of the Puck Failure Theory for Fiber Reinforced Composites Student Name 20 April 2009 ME7501

  2. Introduction • Failure Theories • Compressive Transverse Stress • Shear Stress

  3. Objective • Evaluate the relative performance of Puck’s Failure theory with more traditional theories • Consider udfrc subjected to Transverse and Shear Loading

  4. Failure Theories • Limit • Max Stress/Strain • Interaction • Tsai-Wu • Hill-Tsai • Separate Mode • Hashin-Rotem • Puck

  5. Puck Failure Theory • Separate Mode • Based on Coulomb-Mohr theory for the failure of brittle materials • ‘The stresses on the fracture plane are decisive for fracture’ -Otto Mohr • 2 modes of failure • Fiber • Inter-Fiber • Location of fracture

  6. Puck Failure Theory: Inter-Fiber Failure

  7. Puck Failure Theory: Inter-Fiber Failure

  8. Puck Failure Theory: Master Fracture Body

  9. Puck Failure Theory: AS4/55A

  10. Puck Failure Theory: AS4/55A

  11. Puck Failure Theory: AS4/55A

  12. Puck Failure Theory: AS4/55A

  13. Conclusions • Good performance leading up to and immediately after maximum shear stress point • Good transitional performance between tensile and compressive transverse stress • Poor performance near maximum compressive stress • Requires test data for optimal performance
