Unformatted text preview: Due January 17, 2008 HW1a: Find the energy release rate G for the following DCB (Double Cantilevered Beam) loaded by the concentrated force P . The beam has a thickness b , a height 2h , a crack length a and a Youngs modulus E . . HW1b: Read at least two papers on failure theories authored by R.M. Christensen and published within last ten years. Type a 3-page review comments comparing his theories with those discussed in the class. Due January 24, 2008 HW2a: Two rectangular plates ( E = 10 7 psi, 3 . = and = y 30 ksi) with identical dimensions and thickness. Both have a central hole and are loaded in uniaxial tension. However, one of the holes is slightly larger than the other. Which plate is going to fail first? HW2b: Problem 2.2 on the textbook. HW2c: Problem 2.6 on the textbook. Due January 31, 2008 HW3a: (a) Verify that the primary term of the stress formulae ) , , ( r rr obtained from Williams real-function theory for single-ended crack problem are identical...
