Abstract

This paper presenta a novel method for the experimental determination of the tensile properties of curved members along the direction of their curvature. This consists in preparing tensile specimens made up of two nominally identical (or at least very similar) curved ‘coupon’ components of the material in question, which are placed back-to-back so as to minimize bending strains during testing. The proposed technique is of particular relevance to anisotropic composites, and its application to two types of glass-reinforced plastic sewer linings is reported, showing the good working of the scheme.

Résumé

Cet article présente une nouvelle méthode de détermination expérimentale des caractéristiques de traction d’éléments courbes suivant la direction de leur courbure, qui consiste à préparer des éprouvettes de traction composées de deux ‘coupons’ courbes supposés identiques (ou du moins très similaires), qui sont placés dos à dos de façon à minimiser les déformations en flexion pendant l’essai. La technique proposée convient particulièrement bien aux composites anisotropes. On décrit deux types d’application à deux types de revêtements de collecteur en plastique renforcé de fibres de verre et on montre le fonctionnement satisfaisant du dispositif.
