  1. Nigel Knowles Visiting Professor Cranfield University, UK ( Formerly Director of Technology WS Atkins Consultants, UK ) presented at ASRANET / FENET / IStructE joint meeting on Computational Mechanics in Structural Safety Risk and Reliability June 2003 Concluding Remarks 6

  2. Industry drivers and related issues technical challenges how should we respond? where are we going…...? With acknowledgements to ASRANET and FENET colleagues! 6

  3. pre 1880 - 'rules of thumb' 1880 - energy methods 1960's - special purpose programs – hardware limited 1970's - large scale general purpose analysis codes 1980's - non-linear optimisation computer graphics error measures probabilistic methods 1990's - incorporation into CAE, adaptivity, 'meshless’ f.e.a. Evolutionof Analysis methods in industry

  4. Solvers Element technology (shell elements!) Post processing Software verification Computer resources (Can we fit it on the computer and if so will it solve in a sensible time)? Typical 70’s issues

  5. Moores Law Numerical analysis capability now exceeds our ability to make effective use of it? C B I C Progress

  6. Time to market Operational efficiency Globalisation Environmental concerns Sustainability Safety culture PFI/PPI Longer time frames More holistic approaches Market pressures 6

  7. Whole life management and costing Life extension c.f. new build Assessment of existing structures Ultimate strength analyses Optimisation Commercial risk assessment Treatment of uncertainty Decision making Ensuing business/technical issues

  8. Integration of analysis into business processes Optimisation and decision making Safety qualification Extreme events Confidence Validation and Q A Technology transfer Knowledge dissemination and retention Principal Current Issues 6

  9. Not just a CAD-FE issue! Optimisation wrt to social, commercial and economic issues decision making (under uncertainty) standard procedures data provenance curacy legacy cultural, human and organisational issues Integration of analysis into business processes 6

  10. extreme events (fire, crash, hurricane, earthquake etc) uncertainty handling poorly defined phenomena infrequent occurrences data provenance Stats/probability is not the complete answer life extension geriatric structures Code applicability? Data Safety margins? Safety qualification 6

  11. Validation (“fitness for purpose”) Error minimisation Controlling human error Standards and Q A Confidence 6

  12. Dissemination Education and training Don’t forget managers needs! Legacy knowledge and experience Technology transfer 6

  13. Integration - Broaden horizons! Safety Qualification - Recognise uncertainty Watch for CBIC! Confidence - still immature Technology transfer - more attention to “managers” needs Key messages
