Creep modeling and creep life estimation of Gr.91
International Journal of Materials Research, 2012Abstract The creep behavior and deciding factors for creep life have been investigated for Gr.91 in the temperature range between 450 and 725°C. The longest time to rupture was 68755 h. The creep life is inversely proportional to the minimum creep rate multiplied by the increase in creep rate by strain in the acceleration region for a ...

A coupled creep damage evolution model and creep life evaluation
Materials at High Temperatures, 2018Due to the damage accumulation during creep deformation, creep failure after a certain service time is the most important failure mode for metal structures working at high temperatures.

Creep model of high-strength concrete containing supplementary cementitious materials
Construction and Building Materials, 2019Long-term creep prediction of high-strength concrete (HSC) has been a significant issue in the design of concrete structures. To achieve high performance, supplementary cementitious materials (SCMs) are mixed into HSC. However, few creep models have been

Comparative Creep Life Evaluation of HR3C Using Creep Damage Models
Volume 6A: Materials and Fabrication, 2017Recently, due to both environmental and energy efficiency, the designed life cycle of many power plant have been extended and also their operating temperature increased. When a material is exposed to high temperature over 50% of its melting temperature, it often shows unusual creep behavior in which the long time exposure of high temperature causes a ...

A creep model for frozen sand of Qinghai-Tibet based on Nishihara model
Cold Regions Science and Technology, 2019The tri-axial creep tests of frozen sand with different dry densities and grain size distributions were performed at 0.1 MPa confining pressure at different temperatures.

Modelling of steel creep at high temperatures using implicit creep model
2012Behaviour of steel structures at high temperatures is greatly influenced by the level of creep strains that occur after reaching the temperature above one third of the melting point of steel. For structural carbon steel, this occurs after reaching the structure temperature above 400°C.
