Abstract
Four types of impact specimen, Charpy, Izod, Slender Cantilever and Double Notched Bar, are studied using the technique of dynamic photoelasticity. The growth of fringes with time in low modulus photoelastic material is analysed for each speciment and it is concluded that the stress wave behaviour of the Cantilever geometries and Double Notched Bar offer advantages over the traditional Charpy specimen.
Résumé
On étudie quatre types d'éprouvettes de résilience — Charpy V, Izod, Cantilever mince et Barreau à double entaille — en utilisant une technique de photoélasticité dynamique.
On analyse pour chaque type d'éprouvette la croissance en fonction du temps de franges, en utilisant un matériau photoélastique à bas module, et on conclut que les géométries Cantilever et Barreau doublement entaillé présentent certains avantages sur l'éprouvette traditionnelle Charpy, quant au comportement vis-à-vis de l'onde de contrainte.
