Abstract

Est concerné un ensemble comprenant au moins un élément (200'') en un matériau et au moins un pion de liaison (100'') en un matériau différent, engagé dans un passage dudit élément. Le pion et l'élément présentent, pour être lié, des premières faces respectives d'appui entre eux, et des secondes faces respectives d'appui entre eux, ayant chacune au moins une composante suivant ladite direction d'engagement du pion. Transversalement à la direction suivant laquelle le pion est engagé dans le passage, un jeu existe entre le pion et les premier et second éléments, à température ambiante, et les premières et secondes faces respectives d'appui entre eux du pion et dudit élément sont orientées suivant des premières et secondes surfaces respectives qui présentent entre elles un point de convergence (153'').
