Abstract basic class for Mechanical materials. 'Mechanical' is meant in the 'most general sense', i.e., any material which describes a mechanical (cauchy) stress - deformation relationship (e.g, hyperelastic, hypoelastic, elasto-plastic, visco-elastic materials)
σ = f (σ, dxdX, t, .. ),
formulated incrementally as σ_np = f (σ_n, dxdX_n, dxdX_np, Δt, t_n, .. )
Algorithmic tangent: dσdF = d σ_np d (dxdX_np)
Format:
/ d σ_11 d F_00, d σ_11 d F_10, d σ_11 d F_20, d σ_11 d F_01, \ | d σ_22 d F_00, | | d σ_33 d F_00, | | ... | | ... | \ ... /
such that it can be interpreted as a column major 6x3x3 tensor (4th order, left voigt tensor)
