Visualising Strain

Image 45 October 2017, Star Hydraulics, Tewkesbury

 

 

The day will look at some of the techniques used to visualise strain, both in service and during testing. Knowing strain and load paths is essential to identify with the predicted life and we assume too often the load we apply results in the strain we predicted.
Photo elastic and thermo elastic methods differ in their concept technology and
visualisation of strain. Digital Image Processing (DIP) is the most recent of the these technologies and is three dimensional and more flexible in the range of materials that can be easily covered.
Initial costs of the various systems frequently limits their application but during the day we will demonstrate some more economic and simpler introductory systems that can be used to show the benefit of investing in these technologies under both static and dynamic conditions.
