Fidelity And Credibility of Tests and Simulations [FACTS] is an acronym that I have started to use to describe one focus of my research programme.  According to the Oxford English Dictionary, fidelity means ‘the degree of exactness with which something is copied or reproduced’ and credibility means the quality of being trusted and believed in’.  In engineering physical tests are often used to generate evidence to demonstrate the reliability of simulations.  Hence, one aspect of this research involves establishing and minimising the uncertainty associated with measurements of deformation in structural tests as well as attempting to perform these measurements in real-world conditions.  While another aspect is concentrated on utilising the measurement data in validation processes that demonstrate the fidelity of simulations and provide evidence to support the credibility of computational models.  The following collection of posts provides an overview of ‘FACTS’:

‘Establishing FACTS’ was the title of a lecture that I gave to the local branch of the Institution of Engineering and Technology (IET) on May 30th, 2018.
