FEA is now the predominant tool used in Design by Analysis (DBA). This webinar will review current DBA procedures in popular Codes of Practice and reflect on the use of FEA and any guidance given. Challenges brought about by the historical roots of DBA procedures will be highlighted, before an open discussion and debate is held. The relevance of CCOPPS1 activities to the issues raised in this Webinar will also be highlighted.

Topics for discussion will include:

• Should Codes of Practice reflect the popularity of FEA or remain independent of analysis method? For example should Codes of Practice provide guidance on modelling techniques for fatigue assessment of welds, seals/gaskets and bolted joints? Should Codes of Practice provide modelling and validation advice for use of the Direct Route, including the effects of large deformation, buckling, strain hardening and shakedown?
  
• Does DBA by FEA pose any more of a validation challenge than other DBA methods – from an educational viewpoint, from a legal viewpoint or from a QA viewpoint?
  
• Should the procedures and philosophy inherent in Codes of Practice be modified to make them more amenable to FEA and to reflect the capabilities of modern FEA systems and if so how can they?
  
• Do Codes of Practice inhibit the use of FEA for optimisation, non-deterministic studies and advanced analysis methods in general?
  
• What are the economic drivers for change? What are the real safety concerns? What are the regulators views on these matters?
  
• These issues are not unique to PV Codes – is there a “universal” solution to recognising and embedding FEA into such regulatory frameworks?

The questions and answers raised during this event will be also be posted on a discussion forum , to facilitate further debate by interested parties and also comment by analysts who could not participate in the webinar.

Agenda

Welcome & Introduction
Jim Wood, University of Strathclyde

The Use of Finite Element Analysis in Design by Analysis
Donald Mackenzie and Jim Wood, University of Strathclyde

Q & A Session

Closing

1 This webinar is the first in a series of four sponsored by the CCOPPS project, which is funded by the EU under the Leonardo initiative. The project is focussed on the development of the competence of users of FEA in the power and pressure systems industry. The project partners are the University of Strathclyde, University of Malta, University of Stuttgart, Technical University of Warsaw, CETIM and NAFEMS.
