Elastic properties of fibre reinforced composites

## Structure of the datasets

The data set contains the transverse elastic properties of uni-directional composite materials
with the following details.

### Datasets: D1, D2, D3 and D4

| | Dataset: D1 | Dataset: D2 | Dataset: D3 | Dataset: D4 |
|----------------- |------------------------|-----------------------|------------------------|------------------------|
| **vf** range | [25, 75] | [25, 75] | [10, 25] | [10, 25] |
| **Ecr** range | [5, 250] | [250, 500] | [250, 500] | [5, 250] |
| **X_train** shape| (80, 250, 256, 256, 1) | - | - | - |
| **y_train** shape| (80, 250, 8) | - | - | - |
| **X_test** shape | (40, 250, 256, 256, 1) | (20, 250, 256, 256, 1)| ( 6, 250, 256, 256, 1) | (15, 200, 256, 256, 1) |
| **y_test** shape | (40, 250, 8) | (20, 250, 8) | ( 6, 250, 8) | (15, 200, 8) |

Here,
+ vf: fibre volume fraction
+ Ecr: Elastic moduli contrast, the ratio of fibre elastic moduls to that of the matrix
+ Each of the label arrays contain 8 columns, which are
+ column index => label
`0 => Vf`, Fibre volume fraction
`1 => Em`, Matrix elastic modulus
`2 => NUm`, Matrix Poisson's ratio
`3 => Ef`, Fibre elastic modulus
`4 => NUf`, Fibre Poisson's ratio
`5 => E22/Em`
`6 => E33/Em`
`7 => G23/Gm`
