“…It is appropriate to use 0.55 times the nominal yield stress at a 0.2% offset strain as the yield stress σ|0. And there gave a detailed introduction to the definition of the elastic limit stress in references [47,48]. Q∞ denotes the maximum change value of the yield surface size, indicating the hardening degree, and b denotes the rate of the yield surface size changes with the equivalent increase in the plastic strain.…”

“…The Chaboche model is an advanced material model which considers the Bauschinger effect and can predict the ratcheting behaviour. 19,20 Annealing operations usually cause a high cyclic hardening in the materials. 21 Cyclic hardening is separated into 2 different components named as "isotropic" and "kinematic" parts.…”

The purpose of this research is determining experimentally the characteristics of tension and cyclic plastic behaviours of as‐received and annealed coppers and studying distribution of stress/strain field near the crack tip. Samples made by pure copper were annealed at 420°C for 40 minutes in electric furnace. To determine the properties of the cyclic plastic behaviour, proper tests with symmetric strain‐controlled conditions were performed on standard samples. Chaboche nonlinear hardening model was used to determine the cyclic plastic behaviour of both materials. According to results, annealing process creates isotropic hardening in the copper and also changes its initial kinematic hardening behaviour. Effects of the annealing and hardening on the variations of the stresses and strains around the crack tip were investigated. Also, ratcheting and mean stress relaxations versus number of cycles, inside the plastic region, were studied.

“…This model is applicable in most finite element software in which the nonlinear combined hardening model is supported. Calibration of hardening parameters of materials is usually conducted on specimens exposed to symmetrical cycles, with a constant strain range [14][15][16][17][18][19][20][21]. The resulting parameters are then used in the numerical simulation for solving different engineering problems.…”

To simulate the effect of variable strains on steel grades S275 and S355, an experimental displacement control test of plate specimens was performed. Specimens were tested under monotonic and cyclic loading according to the standard loading protocol of SAC 2000. During experimental testing, strain values were measured with an extensometer at the tapered part of the specimen. Strains obtained by the experimental tests are disproportional to the applied displacements at the ends of the specimens. This phenomenon occurs due to the imperfections of the specimen, hardening of the material, and the buckling behaviour that appears in real structures due to the high deformation experienced during earthquakes. Due to the relative simplicity and wide applicability of the Chaboche hardening model of steel, the calibration of hardening parameters based on experimental test results was conducted. For the first time, calibration of steel hardening parameters was performed following the Chaboche procedure to define the cyclic behaviour with variable strain ranges. The accuracy of the hardening model with variable strain ranges, which were simulated using ABAQUS software, was verified using the experimental results.
