Cracking solution to a material problem

Automotive testing company MIRA has launched a service that can accurately measure how microscopic cracks propagate through materials


Nuneaton headquartered automotive testing company MIRA has launched a service that can accurately measure how microscopic cracks propagate through materials.


MIRA’s fatigue testing system enhances traditional stress/strain fatigue studies by incorporating crack growth analysis as used in the aerospace industry.

MIRA invested £100,000 in new equipment housed inside a climatic chamber where testing can be carried out at temperatures between -150 and 350oC.


Materials manager Andi Clements said: ‘We’re capable of measuring crack growth down in the angstrom range. Our incredibly fine resolution allows us to plot growth at low energy levels far more accurately than anyone in the automotive sector will have seen before.’

David Ensor, MIRA’s senior durability consultant added: ‘These essential fracture mechanics material properties provide one of the most difficult-to-obtain inputs for fatigue engineers. We can now predict the total life of vehicle systems and components.’
