Practice Problem 3-5 (a) Back | Index | Next

Given: Consider a dam constructed of concrete (E = 20 GPa, n = 0.15). Due to the water pressure and the weight of the dam, an element in the dam is subjected to normal stresses in the x-y plane of:

sx = –200 MPa and sy = –400 MPa

Req'd: Determine the normal strain in the out-of-plane direction ez.

ez =  %  (1% error)
