“…But the rock endochronic model proposed by Bazant contains too many parameters without practical physical meaning, which is not conducive to experimental simulations in different rock situations. Subsequently, many scholars applied the endochronic theory to the experimental studies of different materials such as concrete , soil and coal containing gas, and good experimental results were also obtained (Wang and Song 2007;Jeremiah M et al, 2019;Yin et al, 2009). However, the large number of parameters without actual physical meaning in the endochronic constitutive reinforcement function has always been a difficult problem in the study of endochronic theory.…”

Rock materials are often subjected to cyclic loads during construction. A full understanding of the deformation behavior of rock under cyclic loads is of great significance in engineering. In this study, by using the endochronic constitutive model proposed by Valanis, the reinforcement function form and constitutive parameters of the endochronic model are improved. An endochronic plasticity constitutive program for rock based on the finite element method is used to study the mechanical properties of rock under different cyclic loading conditions (of maximum loading stress, amplitude, and confining pressure), and through the use of red sandstone, marble, and basalt, experimental and simulation results are compared to verify the model. The results show that the theory can better simulate the hysteresis loop width and cumulative plastic strain of rock under cyclic loading and, under different loading conditions, the numerical simulation results are consistent with the actual rock experimental law. Therefore, the endochronic plasticity constitutive model in this study can be applied to investigate the influence of cyclic loading on the dynamic deformation behavior of rock.

“…Due to the plastic deformation of components, the geometry is permanently changed. As long as there is a functional relation between these components, their partial or complete malfunction or the overall load-bearing loss might or might not occur [ 4 , 5 ].…”

“…Many authors are currently dealing with the issue of assessment of structural elements in the elastic–plastic regime, considering some form of deformation hardening of classical or modern materials. A few works can be mentioned, e.g., [ 5 , 6 , 7 , 8 , 9 , 10 ], in which the authors deal with the influence of isotropic and kinematic reinforced material in the process of sheet metal forming using simulation methods. The influence of kinematic hardening on the properties of sheets during their drawing is discussed, for instance in [ 6 , 7 ].…”

In exact analyses of bodies in the elastic–plastic regime, the behavior of the material above critical stress values plays a key role. In addition, under cyclic stress, important phenomena to be taken into account are the various types of hardening and the design of the material or structure. In this process, it is important to define several groups of characteristics. These include, for instance, the initial area of plasticity or load which defines the interface between elastic and plastic deformation area. The characteristics also include the relevant law of plastic deformation which specifies the velocity direction of plastic deformation during plastic deformation. In the hardening condition, it is also important to determine the position, size and shape of the subsequent loading area. The elasto-plastic theory was used for the analysis of special compliant mechanisms that are applied for positioning of extremely precise members of the Compact Linear Collider (CLIC), e.g., cryomagnets, laser equipment, etc. Different types of deformation hardening were used to simulate the behavior of particular structural elements in the elastic–plastic regime. Obtained values of stresses and deformations may be used in further practical applications or as default values in other strain hardening model simulations.
