Description and purpose
Virtual Tire Development is an innovative technology that enables the design and testing of a digital tire twin, allowing for virtual optimization of its characteristics before physical testing. The effectiveness of the virtual approach relies on the availability of accurate physical models that describe the rheological properties of the various elastomeric compounds used in a tire under different operating conditions. Additionally, efficient numerical tools capable of handling the complex mechanical problem are essential.

Purpose
The research project has been strategically built to achieve these long-term goals, leveraging the complementary expertise in solid mechanics, materials engineering, and computational mechanics gained by the project members over the years.
Expected results
The main expected outcomes of this research project include the development of analytical and numerical tools to simulate the behavior of elastomers under finite strains, encompassing viscoelasticity, fracture, fatigue, and temperature effects. By enhancing our comprehension and simulation of fracture mechanisms in rubber laminates, we take fundamental steps towards the ultimate goal of fully virtual prototyping and testing of pneumatic tires.
Achieved results
A multi-layer computational tool for failure rupture and delamination has been developed.
