+# ICM Hyperelastic Dataset
+
+This dataset accompanies the paper:
+
+https://arxiv.org/abs/2604.23098
+
+It contains compressed dataset archives used for training and evaluating models for hyperelastic material problems.
+
+## 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-MLB and Test-MLB+ 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.
