Question:
The elastic stress field in the vicinity of a 2-D crack front is given by
Derive the elastic-plastic boundary shape by using the following conditions
(1) Tresca Yield Criterion with v = 0.3 and plane strain.
(2) Von Mises Yield Criterion with v = 0.3 and plane strain.
Plot the results in non-dimensional coordinates x 1 , x 2 divided by
Hint: under plane strain condition, ? 3 = v (? 1 + ? 2 ), where v is Poisson?s ratio and ? 1 , ? 2 and ? 3 are principal stresses.
