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).

Thick-walled cylinder under internal pressure, 2D plane strain (Lamé)

The cylinder of lame-cylinder (a = 10, b = 20, p = 100, E = 210000, ν = 0.3) as a 2D plane strain quarter: one quad8 patch (8 × 16) with mid-side nodes on the arcs, symmetry on x = 0 and y = 0.
