Workshop: Digital volume correlation analysis

Workshop: Digital volume correlation (DVC) analysis: state of the art and applications in materials science

Chair: Gianluca Tozzi (University of Portsmouth)

Venue/Date: Online platform. 26th May 2021 from 2pm Registration

Description: Digital volume correlation (DVC) is rapidly growing in the evaluation of a variety of engineering materials and biomaterials. In fact, with the rapid development of mechanical imaging protocols (4D Imaging) mainly based on X-ray computed tomography (XCT), DVC has become a powerful tool to measure 3D full-field displacement/strain in materials at different dimensional scales. The potential that DVC has to offer to materials science is impressive and ranges from the perfect framework for full-field validation of local properties predictions in computational models (e.g. finite element analysis), to the integration with other imaging techniques (e.g. FIB-SEM) to enable correlative microscopy workflows. However, given the increasing number of DVC software solutions and applications available to date it is mandatory to provide some guidelines for existing and new potential users on different correlation workflows/strategies, which could be more suitable to obtain reliable results for specific research demands.

This workshop therefore aims at including some major DVC solutions presented by both academic and industrial leaders in the field, providing specific insights on use, reliability and further exploitation in different areas of materials science and engineering.

The event is supported by the National X-ray Computed Tomography (NXCT) facility, the Henry Royce Institute, the CCPi (University of Manchester) and the Zeiss Global Centre (University of Portsmouth)

Format: Presentations: These will provide current state of the art on DVC techniques, use and applications in materials science as well as some practical demonstration on DVC software through the main steps of image processing. Technical discussion: This session will open up discussion on DVC solutions and future applications of the technique.

Follow up: New ‘hands on’ DVC workshops: After this event a questionnaire will be distributed to the participants for feedback on presented solutions, which will be used to design and promote other two ‘physical’ workshops at Manchester and Portsmouth taking place once reasonably safe post-covid.

Fees: Free of charge. Registration open soon - contact organiser for list:
