Full-Field Strain Measurement of the Contact Patch via the Inside Tyre Surface

The tyre is the only interface between the vehicle and the road and has thus been the subject of many research studies. An important aspect of tyre research is the development of a smart tyre which can indirectly determine parameters representing the state of the vehicle such as the tyre forces and side-slip angle. In this paper Digital Image Correlation (DIC) is used on the inside surface of the tyre to produce full-field strain measurements of the inside surface of a tyre in contact with the road. The study aims to measure and understand the full-field strain measurements caused by various loading cases with the aim of smart tyre development.
