  • Summary

    There are three broad categories of challenges faced by the Islamic Republic state, namely those emanating from the inside, those exerted on the state from the outside, and those arising from the fraying of the state’s relations with society. In each instance, the state has been able to neutralize any potential threats coming its way through a resourceful combination of foreign policy adjustments, heightened repression, and expansive securitization. Ironically, the comprehensive and punishing sanctions imposed on the state from abroad have only helped further erode the purchasing power of Iranians and have narrowed prospects for international exchanges and globalization. The outcome has been a further strengthening of the state and especially hard-line factions within it, along with a steady disempowering of civil society and increased costs of political opposition. Sanctions have weakened Iranian society and strengthened the state.

  • Le modèle proposé s'inscrit dans le cadre d'une étude sur le comportement micromécanique métallurgique d'un alliage à mémoire de forme (AMF) Cu-Zn-Al durant la transformation martensitique et l'évolution microstructurale.Le modèle montre que la localisation de la déformation plastique après des sollicitations cycliques entraîne des modifications dans les propriétés mécaniques et thermiques. L'originalité du modèle permet de coupler entre les deux transformations de structures en montrant les mécanismes de déformation nécessaires lors des transformations.
