Abstract

Sac gonflable dans lequel des évents non circulaires remplacent les traditionnels évents circulaires. En général, les évents confèrent une géométrie asymétrique à la structure du sac et induisent une concentration de contrainte dans la géométrie. Les recherches menées sur le déploiement des sacs gonflables ont montré que les évents circulaires s'allongent pendant les premières phases de déploiement. Cela provoque des concentrations de contrainte aux deux points circonférentiels du cercle lorsque le matériau est déformé. Sur la base de cette découverte, les inventeurs ont déterminé qu'un évent non circulaire, tel qu'une ellipse ou un rectangle, serait préférable pendant les premiers stades du déploiement étant donné que cet évent non circulaire possède une position plus naturelle pendant la déformation précoce, ce qui lui évite d'induire une déformation supplémentaire dans cette région.
