Macroscopic stress-strain dataset of a hyperelastic heterogeneous material

The dataset used in "Surrogate computational homogenization enhanced by partition-of-unity RBF Interpolation with decision trees, Yosuke Yamanaka, Norio Hirayama, Kenjiro Terada"
The data is generated by numerical simulations referred to as "Numerical material tests" for the unit cell of microscopic structures.
mesh.vtk: FE mesh of the unit cell.

- Each line corresponds a data point.
- The columns correspond to $\tilde{U}_{11}-1$, $\tilde{U}_{22}-1$, $\tilde{U}_{33}-1$, $\tilde{U}_{12}$, $\tilde{U}_{23}$, $\tilde{U}_{31}$, $\tilde{S}_{11}$, $\tilde{S}_{22}$, $\tilde{S}_{3}$, $\tilde{S}_{12}$, $\tilde{S}_{23}$, $\tilde{S}_{31}$.
