| Summary: | A critical review of the problems asociated wth the design of an ideal platen for uniaxial loading tests is presented. A method of design based on an analytical approach is then formulated. The method permits a liberal choice of material for constructing the platen, which consists mainly of a low modulus plug confined in a metallic ring. A finite element approach has been employed to substantiate the proposed method. Practical design aspects are also discussed. On présente une analyse critique des problèmes associés au dessin d'une plaque de tête idéale pour des essais de chargement uniaxial. Une méthode de calcul basée sur une approche analytique est formulée. La méthode permet un vaste choix de matériaux pour la fabrication de la plaque qui consiste essentiellement en un élément à faible module confiné dans un anneau métallique. Une analyse par éléments finis a été utilisée pour confirmer la méthode proposée. Les aspects pratiques du design sont également discutés. Peer reviewed: No NRC publication: Yes |
