Abstract

La présente invention concerne un procédé, un dispositif et une machine d'essai de flexion pure, éventuellement alternée. Deux exemplaires, mutuellement identiques, d'une même éprouvette (1) sont soumis à des flexions antagonistes éventuellement alternées, en conservant une symétrie mutuelle par rapport à un point (22), sous l'action de deux ensembles moteurs commandés (21) libres de se déplacer l'un par rapport à l'autre. Les efforts parasites introduits dans les deux exemplaires de l'éprouvette (1) en cours d'essai sont réduits à un minimum, et le comportement de l'éprouvette (1) en flexion pure peut être étudié avec une précision accrue.
