# ICM Hyperelastic Dataset

This dataset accompanies the paper:

https://arxiv.org/abs/2604.23098

The corresponding code is available at:

https://github.com/scaling-group/icm-hyperelastic

It contains compressed dataset archives used for training and evaluating models for hyperelastic material problems.

Because the data are provided as compressed `.tar.zst` archives, the Hugging Face Dataset Viewer is not available for this dataset.

## Dataset Splits

The archive names indicate the split and the mechanical setting:

| Name pattern | Meaning |
| --- | --- |
| `train` | Training set |
| `val105` | Test-ID |
| `val11` | Test-M |
| `val13D` | Test-MGL and Test-MGL+ |
| `pe` | Plane strain |
| `ps` | Plane stress |

For example:

- `dataset-train-pe.tar.zst`: training set under plane strain
- `dataset-train-ps.tar.zst`: training set under plane stress
- `dataset-val105-pe.tar.zst`: Test-ID under plane strain
- `dataset-val11-pe.tar.zst`: Test-M under plane strain
- `dataset-val13D-pe.tar.zst`: Test-MGL and Test-MGL+ under plane strain

## Usage Notes

Except for the experimental validation results, which use the plane-stress dataset for training, all other results in the paper use the plane-strain dataset.

In the file names:

- `pe` denotes plane strain.
- `ps` denotes plane stress.
