Minimizing risk when selecting or changing materials

Guest speaker: Mark Yeoman, Continuum Blue

Watch this webinar to find out how to reduce the cost and risk associated with the specification of a new material, avoiding extensive test, modelling, characterization and prototype programmes. Dr Mark Yeoman, of Continuum Blue, will talk about how he used CES Selector to identify candidate materials for chemical containers and inkjet cartridges.

Rational Selection in CES SelectorWhen selecting materials, companies tend to gravitate to the materials they’ve used before. There are good reasons for this, as they’ve built up knowledge on how the materials performance in service, they know how to process them, and the supply chain is established. However, there are often times where they have to consider a new material. This could be due to supply issues, materials become obsolete, or their products have evolved to such an extent that the existing materials cannot handle the higher operating conditions (temperatures, speeds, pressures, etc). In these cases, how do they minimize the risks associated with the specification and qualification of new materials? The risks include, in development: not achieving expected performance, extended development cycles and rising costs; and in production: high scrap rates, increased maintenance/warranty returns, customer dissatisfaction, product recalls and damage to brand reputation.

Typically, companies reduce these risks by carrying out extensive test, modelling, characterization and prototype programmes, and by evaluating multiple materials. This is both time consuming and expensive. This webinar will show how the costs and risks associated with the specification of a new material can be reduced using the data and tools in CES Selector to quickly compare materials and identify the most promising candidates for a target application.

Continuum Blue presentation: The material selection process for chemical containers or cartridges has some interesting design challenges to overcome, especially when trying to reduce weight and material volume and their carbon footprint. Not only do they need to be inert to the chemicals they hold, but they also need to hold up in extreme environments, maintain their shape at high temperatures, and hold extreme variations in internal pressures (especially alcohol based chemicals), but they need to maintain their toughness below freezing. This combined with novel cap and seal designs, an initial material selection study is essential to eliminate non-feasible materials and provide a number of feasible materials, which can be assessed further using multiphysics models and the finite element method.

About the presenters

Dr. Mark Yeoman is founder of Continuum Blue, a consulting firm based in the United Kingdom, providing multiphysics simulation & consulting services to various companies, including Jaguar Land Rover, Rolls-Royce and GSK. He has a degree in engineering and a PhD in applied mathematics & numerical methods. His postgraduate research focused on the design and optimisation of cardiovascular implants using computational techniques for US medical device corporate, Medtronic Inc. where his research resulted in a number of novel implant designs and patents, which are in use today. Following his postgraduate studies, he lectured an undergraduate dynamics course in engineering and consulted on medical and engineering projects, before starting Continuum Blue.

Dr. Charlie Bream is the Senior Product Manager for CES Selector at Granta Design. After completing his PhD on recycling of thermoset composites at Brunel University, he spent 14 years in industry working on the development of lightweight materials and structures for British Aerospace (Space Systems), Pera International, and NXT before joining Granta in 2007.
