Abstract

در شصت سال گذشته، روش های رهایی پویا تحول های فراوانی یافته اند. در بیشتر زمان ها، این فرایند های صریح و تکراری برای حل معادله های خطی و ناخطی حاکم بر رفتار سازه ها به کار می روند. در بخش اول این مطالعه، رابطه سازی های معمول مرور می شوند. پایه های ریاضی و نیزمفهوم های فیزیکی به طور خلاصه شرح داده خواهند شد. سپس، شرح همه ی عامل های رهایی پویا، مانند: جرم ساختگی، میرایی ساختگی، گام زمانی ساختگی و حدس نخستین، می آیند. افزون بر این ها، به چگونگی حل مساله های سازه ها با شیوه های جنبشی و لزجی پرداخته می شود. سرانجام، روش های کنونی و راستاهای پژوهش آیندگان واکاوی می گردند. دربخش دوم، کاربردهای روش های رهایی پویا در رشته های مهندسی مرور خواهند شد. این موضوع، توانایی بالای فرایند رهایی پویا در حل مساله های مهندسی را آشکار می سازد.

Keywords
