“…The sizes of a small number of subgrains increase during the creep process due to subgrain merging. A creep activation energy of 123.2 kJ/mol is close to that of the lattice self-diffusion in aluminum, implying that a lattice self-diffusion mechanism is dominant at 150 C/90 MPa (Figures 4 and 5), [59].…”

This chapter presents a useful literature reviews and applied solved problems that focus on the creep phenomenon and behavior of it in the solids. Various insights and available studies are reviewed and investigated regarding the creep behavior analysis in three categories such as analytical, numerical and experimental methods. In addition, novel and recent findings are presented in this chapter such as predicting and obtaining the viscosity of the solids at high temperatures using steady state creep phenomenon (i.e., introducing a simulation and analogy between creeping solids and viscous fluids).

The working condition of the CID (current interrupt device) has an important impact on the safety of the prismatic lithium-ion batteries. One of the important factors that causes the failure of the prismatic power battery is the overturning of CID due to material creep. The tensile and creep tests of the MFX2 aluminum alloy which is the material of CID were designed. Based on the experimental data the isotropic hardening multilinear elastic-plastic constitution and creep constitution at the battery working temperature were established. The constitutions were also verified by the notch test. The finite element model of the CID and the cap was established to analyze the effect of creep on the failure behavior of the CID throughout life. The simulation tests in the constant temperature and constant load of CID is designed. The simulation results showed that the constitution characterizes the basic mechanical properties of the CID reasonably. During the life of the CID, the creep behavior would go through the fast stage firstly and then fall into the slow steady-state stage. The creep effect of the material would cause the CID to overturn in advance, overturning pressure would be reduced, the life of the power battery would also be reduced.

“…Although Nabarro considered these theories "unconvincing" [8], they could nevertheless represent a basis to develop new creep models for more complex materials. Yet, the creep community was almost invariably satisfied with using the power law in its phenomenological form to describe the response of innumerable materials, even with extremely complex microstructures (see [9][10][11][12][13][14][15][16] for just few very recent examples). In these cases, n, Q and A are calculated by a best fitting procedure of the experimental data and cease to have a direct correlation with microstructural phenomena.…”
