Materials testing

The response of a material under different levels of stress is used to investigate its suitability for different engineering applications and model its response under realistic conditions. This applies to rock, but also to most solid materials. Passive and active acoustic monitoring provides a 4D image of the changes in the material during deformation tests, from elastic properties to the initiation and growth of cracks


Acoustic Emission and Ultrasonic survey monitoring provide essential input for numerical models, material characterisation and advanced studies of brittle and elastic materials

ASC provides a full integrated processing service from array design, through data acquisition, processing and reporting to advanced interpretations with dynamic numerical models to better understand the deformatioon process and the growth and activation fractures in materials. ASC’s advanced analysis of Acoustic Emission and Ultrasonic survey data yields high resolutino information on fracture initiation and growth, stress-strain relationship and temporal evolution of elastic properties under stress tests. ASC provides the following services for researchers and industry involved in material characterisation:

  • High-sampling rate data acquisition systems, including capability for simultaneously work in streaming and triggered mode, to provide real-time fedback and record the full acoustic stream. Our systems can periodically switch between passive and active mode to maximise the information acquired, surveying changes in elastic wave velocity accross the material. 
  • Advanced post-processing, analysis and interpretation of client data using a range of techniques and software functionality developed in-house.
  • Design, optimisation and quality check of acoustic monitoring arrays.
  • Staff training on the use of our acquisition systems and on the processing and analysis of the AE data
