The right answer is(1) ●Eqn.(??) is wrong because o22≠0 due to Poisson’ s effect Eqn.(?? )is correct, 633+0 due to the mposed displacement,∈11≠0 due to pois sons effect and E22=0 because of the plane strain condition Eqn.(?? ) is wrong, it contradicts Eqn. (??) Eqn.(?? ) is correct, the plane strain condi tions are actually materialized via u?=0The right answer is (1) ++++ . • Eqn. (??) is wrong because σ22 6= 0 due to Poisson’s effect. • Eqn. (??) is correct, �33 6= 0 due to the imposed displacement, �11 6= 0 due to Pois￾son’s effect and �22 = 0 because of the plane strain condition. • Eqn. (??) is wrong, it contradicts Eqn. (??). • Eqn. (??) is correct, the plane strain condi￾tions are actually materialized via u2 = 0
