Creep: Time‐dependent brittle deformation in rocks

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

Creep Deformation of Ice

Knowledge of the creep properties of ice often is needed in field and theoretical studies of the flow and deformation of glaciers, ice shelves, and ice sheets. Recently many of the icy moons in the solar system have become much better known as a result of the successful deep-space probe missions. An understanding of the physical processes that take place within them requires information about t...

Fluctuations and scaling in creep deformation.

The spatial fluctuations of deformation are studied in the creep in Andrade's power law and the logarithmic phases, using paper samples. Measurements by the digital image correlation technique show that the relative strength of the strain rate fluctuations increases with time, in both creep regimes. In the Andrade creep phase characterized by a power-law decay of the strain rate ϵt∼t(-θ), with ...

Radiation Effects in Metals: Void Swelling and Irradiation Creep

Until about 1967 the most detrimental radiation effect expected to be suffered by the stainless-steel cladding of the fuel elements of the projected liquid-metal-cooled fast breeder reactor (LMFBR) was embrittlement due to exces­ sive hardening at low temperatures or helium agglornrration at grain boundaries at high temperatures, These problems, however, were at least qualitatively understood, ...
