WEBINAR: The Importance of Mechanical Material Properties and a Critical Appraisal of Mechanical Testing Methods

Date: 10 June, 1-2pm Presenter: James Dean, Plastometrex


This presentation concerns the strength of metallic materials, mechanical testing and mechanical test data. We will first outline what strength really means, and we will review the common tensile test, discussing differences between true and nominal values, misunderstandings around ductility values, necking instabilities, and some limitations of the tensile test. We will also cover hardness tests, and will explain why hardness numbers can be vague and ambiguous, despite their common and widespread usage in non-destructive testing. The third technique we will cover is Indentation Plastometry, an indentation-based test technique that can measure full stress-strain curves and metal strength parameters from measured indent shapes using inverse finite element methods. Some example case studies will also be shown.

James Dean

James has an undergraduate degree in Materials Science from Imperial College, London, and a Masters in Gas Turbine Engineering from Cranfield University, where he was supported with a Rolls Royce UTC scholarship. He has a PhD from Cambridge in Materials Science, where he subsequently held Research Assistant and Senior Research Associate positions. He then moved to the Centre for Scientific Computing at the Cavendish Laboratory, Cambridge, where he was Co-ordinator of a Centre for Doctoral Training in Computational Methods for Materials Science. In 2012 he founded Double Precision Consultancy, a company specialising in the provision of advanced mathematical modelling services that he sold to Element Materials Technology in 2021. He co-founded Plastometrex in 2018 and is the current CEO.

EXHIBITION: Instrumentation, Analysis and Testing Exhibition 2021

Date: 14 September 2021, Silverstone Race Circuit


The Instrumentation, Analysis and Testing Exhibition has become a significant event in the engineering year and with visitors travelling from across the UK it is seen by many as the go-to event for testing and analysis technologies. Returning to the Silverstone Wing at Silverstone Race Circuit in September 2021, the exhibition is an opportunity to visit the 65 exhibitors to see the latest equipment and technologies as well as being a great meeting point for the exchange of ideas and contacts. The event is aimed at companies and individuals with an interest in the field of engineering involving measurement, analysis, testing and prediction. It covers many sectors including Automotive, Aerospace, Motorsport, Rail, Off-Highway, Mechanical Handling, Civil Engineering, Industrial and Power Generation.

Mini Seminars

There will be a number of mini seminars taking place throughout the day on a given theme. This will be announced in the coming months.


Attendance is free and visitors receive complimentary refreshments along with free parking.
