Abstract

A nonlocal damage field theory is proposed and a response model of nonlocal elastic damage is given. A simulating experiment using aluminum alloy plates with arrays of holes shows that the load bearing capacity of a plate varies with angle γ between array and loading direction. The characteristics and attenuation lengths appreciably affect the constitutive equations.

Résumé

On propose une théorie du champ d'endommagement non local et on donne un modèle de réponse à un dommage non local élastique. En utilisant des tôle en alliage d'aluminium pourvue de rangées de trous pour une expérience de simulation, on montre que la capacité de résistance d'une tôle varie avec l'angle γ formé par une rangée de trous avec la direction de mise en charge.
