Bridgestone wanted a technology that could perform accelerated usage and testing across its various tyres and industrial rubber products, like conveyor belts and rubber tracks.

Dynamet (DYNAmic Multi-axial Elastomer Testing) is an enabling technology for rubber testing and analysis developed at Dublin Institute of Technology (DIT). It uses bubble inflation technology to enable rubber stress testing under various conditions.

Dynamet was developed by researcher Dr Niall Murphy, a Lecturer in the School of Manufacturing and Design Engineering at DIT Bolton Street. Niall has a long track record in designing test apparatus for rubber components. Bridgestone, the largest manufacturer of tyre and rubber products in the world, licensed the technology to test new materials and designs for worldwide deployment and improve the time to market of its tyres. The technology allows Bridgestone, which produces in the region of 500 million tyres each year, to carry out accelerated usage and age testing on tyres and other products and to immediately test new materials and designs. DIT researchers are continuing to work with Bridgestone on the technology.

DIT Hothouse saw the immediate commercial application of Dynamet and protected the intellectual property. A commercialisation strategy and marketing campaign attracted interest from tyre manufacturers and DIT Hothouse negotiated a non-exclusive licence to Bridgestone. DIT Hothouse is also exploring other commercial applications for the Dynamet platform technology.
