- •
The elastic fields of a core-spreading dislocation in bimaterials were derived with respect to three fractional models.
- •
These dislocation models can be used in developing strengthening models and discrete dislocation dynamics models.
- •
The linear distribution core model is simple and accurate in capturing the elastic fields.
- •
The core-spreading has significant influence on the elastic fields when a field point is within 2.17 times the core width.
