تحلیل ارتعاشات عرضی یک تیرتیموشنکو ویسکوالاستیک تحت حرکت محوری با روش اغتشاشات (multiple scale)

در این تحقیق ارتعاشات عرضی یک تیرتیموشنکو ویسکوالاستیک تحت حرکت محوری با روش اغتشاشات، مورد ارزیابی قرار گرفته است. برای توصیف رفتار ویسکوالاستیک از مدل استاندارد جامد خطی که در آن از مشتق مادی زمانی استفاده شده است، کمک گرفته شده است. جنس تیر در برش از مدل ویسکوالاستیک پیروی می کند و در فشار تراکم ناپذیر است. سرعت محوری به صورت متوسط ثابت با تغییرات هارمونیک کوچک مشخص شده است و معادلات حاکم بر...
