چکیده
In this investigation the fracture parameters of compacted clay specimens has been obtained. Three point bend tests were used to find the fracture parameters of compacted clay specimens. One of the characteristics of these tests is that instead of a stress-controlled method a displacement controlled one has been used. Therefore by using these tests the softening portion of the load-displacement curve was obtained. By comparing the loaddisplacement curves obtained from a finite element analysis with the ones obtained from the experiments the desired fracture parameters have been calculated. It was also noted that by using a linear softening law for the cohesive zone model a very good agreement between experimental and numerical results has been achieved.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
