Simulative Accelerated Creep Test on Gleeble

Materials Science Forum, 2010
The simulative accelerated creep test (ACT) on Gleeble thermal-mechanical simulator was developed as a response to an overall need of gaining in a short time useful physical data for estimation of long-term behaviour of materials exposed to operation at elevated temperatures.

Accelerated creep resistance of thermal barrier coated superalloy

Materials Letters, 2006
Abstract This paper deals with accelerated creep properties of thermal barrier coated (TBC) Superni C263 alloy used as a candidate material in combustion chamber of aero engines. Results reveal that the life of the TBC composite under accelerated creep is substantially higher compared to that of the bare substrate.

Creep behavior of geosynthetics using confined-accelerated tests

Geosynthetics International, 2011
ABSTRACT: The creep behavior of geosynthetics has commonly been determined using standardized creep tests, which are time consuming and very expensive. In addition, these tests involve the use of in-isolation specimens. Thus they are not likely to consider the overall effect of soil confinement.

Threshold stress for cyclic creep acceleration in copper

Journal of Materials Science, 1988
The phenomenon of cyclic creep acceleration (CCA) is well known. Also, it has been observed experimentally that there exists a peak stress level above which CCA begins to occur. For copper the value of this peak stress is known to be independent of cyclic stress conditions such as stress amplitude and frequency.

Extrapolation of Sigmoidal Creep Curve by Strain Acceleration Parameter

Key Engineering Materials, 2013
It has been widely accepted that the creep characteristics at high temperatures are mainly evaluated by a minimum creep rate and a time to fracture. Although, a shape of creep curve may vary depending on deformation conditions, the apparent minimum creep rates may become the same value.

Creep behavior of geosynthetics by temperature accelerated testing

2017
Прогнозирование ползучести геосинтетических материалов является необходимым для определения расчетного срока службы конструкций с их применением. В данной работе были проведены испытания на ползучесть георешеток и геополотен, изготовленных из двух основных типов синтетических полимеров - полиэфира и полипропилена, используемых при производстве ...

Study on Accelerated Creep Properties and Creep Damage Constitutive Relation for Volcanic Breccias

2013
In order to know about the accelerated creep properties of volcanic breccias, triaxial compression rheological experiments are carried out on rock servo-controlled triaxial rheology equipment. Based on the experimental results, the accelerated creep phase of creep curve of volcanic breccias is analyzed.

Accelerated characterization for long-term creep behavior of polymer

SPIE Proceedings, 2008
ABSTRACT Based on the observation that high stress results in increasin g creep rate of polymeric material, which is analogous to the time-temperature equivalence, where high temperature accelerates the process of creep or relaxation of polymer, the time-stress equivalence is investigated.

Conventional and accelerated creep tests on nonwoven needle-punched geotextiles

Geosynthetics International, 2005
Nonwoven needle-punched geotextiles are prone to creep deformations when subjected to sustained tensile loads. Creep characterization of these materials is particularly relevant in countries such as Brazil, where nonwoven geotextiles are often used in soil reinforcement applications.

Grain Boundary Analysis of HT9 Steel after Accelerated Creep Testing

MRS Proceedings, 2010
AbstractFerritic/martensitic steels are attractive materials for use as components in nuclear reactors because of their high strength and good swelling resistance. Grain boundary specific phenomena (such as segregation, voiding, cracking, etc) are prevalent in these materials so grain boundary character is of primary importance.
