Abstract

L'invention concerne un procédé et un appareil de simulation d'un processus de soudage au moyen de modèles intégrés (100) interconnectés par un outil (114) d'interconnexion afin de déterminer les contraintes et les déformations d'une matière soumise à un processus de soudage. Le procédé et l'utilisation de l'appareil consistent à définir un modèle géométrique d'un ensemble de matières à souder, à définir un ensemble de coordonnées d'éléments et de noeuds du modèle géométrique (102) pour une maille d'analyse par éléments finis, à délivrer les coordonnées de la maille d'analyse par éléments finis à un modèle (106) d'analyse thermique, le modèle (106) d'analyse thermique comprenant un modèle (108) de solution analytique et un modèle (110) d'analyse par éléments finis, et à déterminer une analyse thermique du processus de soudage, l'analyse thermique générant en réponse un historique thermique du procédé de soudage. Le procédé et l'utilisation de l'appareil consistent également à délivrer l'historique thermique du processus de soudage à un modèle (110) d'analyse structurelle, et à générer une analyse structurelle du processus de soudage en fonction de l'historique thermique.
