[ 1 ] - پیش بینی رفتار پیش و پسا-گسیختگی ورق‌های دایره‌ای تحت بارهای دفعی با استفاده از تحلیل‌های حدی تغییر شکل (علمی-پژوهشی)

Two effective quasi – static models are presented to consider pre and post- failure behaviors of the clamped circular plates subjected impulsive loads based on upper bound limit analyses of deformation. In first model, it is assumed that final profile is considered to have a conical shape, which is represented by radial and vertical motions of a single peripheral plastic hinge permanent deflect...
