Abstract
The paper considers a top-down systems approach to the wealth creation process starting at the marketplace, progressing to a design specification, the concept design phase and, through detailed design and manufacture, to delivery of the component or system to the client. At all stages of the process the need is considered for data and in particular materials data. Whilst the paper refers to the special features associated with the quality of materials data required at the concept stage of design, consideration is also given to the type of data required to underpin product innovation and technological forecasting. The bulk of the paper considers the materials data requirements for supercomputer simulation of the behavior of components in service and of products where the material is created and then used in service. The latter situation is considered via the optimization of the selection of materials for a high- temperature weldment in a pressurized steam pipe; and also via the assessment of the performance of a tension panel, containing a central circular hole, fabricated from a tough ceramic fiber-ceramic matrix composite. These examples show the diversity of requirements of materials data in supercomputer simulation at the detailed design stage. In the examples considered, reference is made to visualization and video animation to transmit two dimensional screen images of the time variation of field plots of stress and internal damage variables which can be interpreted satisfactorily by a range of cross-disciplinary specialists. Conclusions are made on the importance of linking the structure and accessibility of databases with the need to provide guidance from physics-based mechanism maps for deformation, damage and fracture.
Résumé
On considère une approche systémique descendante du processus de création de richesse, en partant du marché pour présenter au client un design détaillé et la réalisation industrielle des produits résultants. Cette démarche passe par la spécification de design et par la phase conceptuelle du design. On considère dans toutes les étapes du processus le besoin de données et, en particulier, des données sur les matériaux. Bien que l’on se concentre sur les aspects spéciaux associés à laqualité des donnees sur les matériaux nécessaires au stade conceptuel du design, on considère aussi les types de données sur lesquels sont basées l’innovation de produits et les prévisions technologiques. L’essentiel de cet article est orienté vers les exigences en données sur les matériaux nécessaires dans les simulations sur superordinateur du comportement des composants en service, ainsi que sur des produits imposant la création de matériaux en vue de leur utilisation courante. Dans ce dernier cas, on considère l’optimisation de la sélection des matériaux pour la soudure à haute température d’un circuit de vapeur sous pression; de meme on évalue la performance d’un tableau de tension contenant un orifice central circulaire, fabriqué à partir d’une matrice composite de fibres solides de céramique. Ces exemples sont utilisés pour souligner la diversité des exigences des données sur les matériaux dans la simulation sur superordinateur au niveau de la conception détaillée du design. Dans ces cas, nous nous référons à la visualisation et à l’animation vidéo pour transmettre des images d’écran en 2 D des variations temporelles de champ des sites de tension et des variables de dommage interne dont l’interprétation est acquise de façon satisfaisante grâce à la contribution de specialistes interdisciplinaires. En conclusion il est essentiel d’associer étroitement la structure et les fonctions d’accessibilité des bases de données à la nécessité de procurer aux spécialistes des cartes des mécanismes d’origine physique pour les déformations, les dommages et les fractures.
