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).

Plate with a circular hole in tension, 2D plane stress (Kirsch)

The plate of kirsch-plate as a 2D plane stress model: a quarter of half-width 30 with a hole of radius 1, two quad8 patches around the hole (40 × 16 each, graded 40 : 1 towards it, mid-side nodes on the arc), symmetry on x = 0 and y = 0, a traction of 1 on x = 30.
