1.2. Material properties#

Elastoplastic material without work hardening

\(E=3.E+07\mathrm{MPa}\)

\(\nu =0.3\)

\({\sigma }_{y}=3.E+04\mathrm{MPa}\)

1.3. Boundary conditions and loads#

Point \(A\): \({u}_{x}=0\)

Point \(B\): \({u}_{y}=0.\)

The following loading (= internal pressure) is applied:

\(p=1.737{p}_{0}\) (near the ruin) with \({p}_{0}=658.257\mathrm{MPa}\) (end of the linear regime)

Load \(p\) is applied in 50 identical increments.
