The 9th International Conference on Computational Methods and Experiments in Material and Contact Characterisation took place in Lisbon, Portugal from 22nd to 24th May 2019. The Conference was organised by the Wessex Institute, UK, represented by Santiago Hernandez, Lisbon University, Portugal, represented by Rui Vilar, the University of Windsor, Canada, represented by Derek Northwood and the University of Groningen, The Netherlands.

The conference is a result of a series of meetings that started as early as 1993 in Southampton on contact mechanics and previous meetings on the wider field of material characterisation, dating from the 2003 conference in Santa Fe, New Mexico. It is well-established and always attracts a wide international spread of delegates. The aim of the conference is to facilitate interaction between the research and industrial community and discuss the latest developments in this rapidly advancing field. The meeting responds to the demand for high quality production for both industry and consumer, which has led to rapid developments in materials science and engineering. This requires the characterisation of the properties of materials.
