ELASTICITY & PLASTICITYTime: 2 Hours
Max. Marks: 25Answer any Four questions.
Assume suitable data wherever necessary.
1. Apply a general polynomial solution of governing differential
equation to the case of bending of cantilever loaded at the end,
and obtain stresses, strains and displacements.2. From the general
solution of symmetric stress distribution problem in polar
coordinates derive the stresses in the case of pure bending of
curved bar?
3. Explain the stress distribution in rotating disk and the
effect of a hole at the center of disk?
4. How does a circular hole effect the stress distribution in a
plate under uniform stress distribution .Explain and sketch the
stress distribution?5. If an infinite large plate is loaded at the
straight boundary with a concentrated point load .Derive the radial
solution for the stress distribution in the plate .sketch the
variation of stresses?
6. For the following stress tensor generate a stress ellipsoid
and obtain principal stresses principal planes and hence formulate
the stress invariants
