Creep strain modeling for alloy 690 SG tube material based on modified theta projection method
Nuclear Engineering and Technology, 2022 During a severe accident, steam generator (SG) tubes undergo rapid changes in the pressure and temperature. Therefore, an appropriate creep model to predict a short term creep damage is essential.

Contemporary analysis and numerical simulation of revisited long-term creep tests on reinforced concrete beams from the Sixties [PDF]
, 2017 The stresses and deformations in concrete change over time as a result of the creep- and shrinkage deformations of concrete. Different material models are available in literature in order to predict this time-dependent behaviour.

Creep failure in a threshold activated dynamics: Role of temperature during a sub-critical loading [PDF]
, 2019 Creep is a time-dependent deformation of solids at relatively low stresses, leading to the breakdown with time. Here we propose a simple model for creep failure of disordered solids, in which temperature and stress are controllable.

Creep Rate and Creep Model of Rockfill
Procedia Engineering, 2012 AbstractDue to the test duration restriction, not only the creep strain but also the creep rate should be considered to establish the creep model of the rockfill. The creep rate decides whether the creep model deviates from the actual strain after the test duration.

Creep Characteristic Test and Creep Model of Frozen Soil
Sustainability, 2023 In order to research the creep deformation characteristics of frozen soil and the effect of various influencing factors on creep, indoor uniaxial creep tests were carried out on frozen soil specimens at temperatures of −5, −4, −3 and −2 °C under loads of 0.25, 0.5, and 0.75 σt, respectively.
