The geometrically nonlinear Cosserat micropolar shear-stretch energy. Part II: Non-classical energy-minimizing microrotations in 3D and their computational validation

Andreas Fischle, Patrizio Neff

In any geometrically nonlinear, isotropic and quadratic Cosserat micropolar extended continuum model formulated in the deformation gradient field $F=\nabla \phi :\Omega \to G{L}^{+}(n)$ and th…
