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).

Uniaxial tension of a J2 bilinear-hardening cube to large strain (explicit)
A unit cube of one hex8 (one-point, hourglass control), steel-like (E = 200000, ν = 0.3, σ_y = 250, H = 2000, ρ = 7.8e-9), held by symmetry on three faces and stretched on the fourth to λ = e^0.2 over 0.01 s (quasi-static), lateral faces free: uniaxial stress at a logarithmic strain of 0.2.
