jyvikoandClaude Opus 5.5 96c9992c92 oracle: 2D cases (Kirsch plane stress, Lamé plane strain and axisymmetric, rotating disc and cylinder, NAFEMS LE1 with quad8) and J2 uniaxial explicit
The pending 2D LE1 case becomes a real one; the plasticity cases stay
pending with what they still need (static J2 for the collapse pressure,
the transcribed measurements for the Taylor bar).

NAFEMS LE1 elliptic membrane with 2D plane stress elements (quad8)

The membrane of nafems-le1 with plane stress quad8 elements (thickness 0.1): one patch between the two ellipses, 24 × 48 elements graded 4 : 1 towards the hole, mid-side nodes on the ellipses.
