Question:

For the Flamant problem with only normal loading, explore the strain energy in a semicircular area of radius R centered at the loading point. Refer to the discussion in Section 5.8, and use relation (6.1.10) to explicitly determine the strain energy. Comment on whether the expression is singular or not as R→0.

Equation 6.1.10

U(a) = 1+v 2E 1+v (0 + 03 + 0  + 213y + 232 +2x) - 2 (0x+0 +0 2E ijo ij V 2E jjkk (6.1.10)

Data from section 5.8
