“…The definition and optimisation of advanced constitutive model parameters on the basis of the different experimental tests result is a tedious and complex procedure and also requires conversance and experience of parameter determination. Recently, various methods were introduced for the parameter determination of Chaboche model, and each of them claimed to be more efficient . However, in this paper the optimised parameters of CH3 model (C 1 , C 2 , C 3 , γ 1 , γ 2 , γ 3 ) were calibrated on the basis of the method, which are explained in literature in more details and are presented in Table .…”

In this paper strain ratcheting in cold expanded flat plate of Al-alloy 2024-T3 in double shear lap joints was studied both experimentally and numerically. In the experimental part, two types of symmetric strain-controlled and asymmetric stress-controlled cyclic tests were performed. Also, the cold expanded double shear lap joints subjected to cyclic stress-controlled tests. The required parameters for simulating the cyclic plastic behaviour of Al-alloy 2024-T3 were obtained on the basis of the experimental responses. In the numerical part, a combination of nonlinear isotropic and nonlinear kinematic hardening model (Chaboche) was implemented in the commercial finite element code of ABAQUS, using the subroutine UMAT written in FORTRAN. The results of simulations give an accurate prediction of ratcheting for all types of loading. The obtained results show that increasing the mean stress increases the strain ratcheting. It is clearly shown that the cold expansion process decreases the magnitude of strain ratcheting remarkably compared with "as drilled" specimens and the decrease is bigger for larger cold expansion sizes.Also, it is shown that the middle plane has the highest amount of ratcheting compared to the pin entrance plane and exit plane of the plate hole.

“…where d ij = incremental back stress d ij p = incremental plastic strain c = material parameter They can describe stable loops in cyclic loading, including the Bauschinger effect. However, for a prescribed uniaxial stress cycle with a mean nonzero stress, they fail to distinguish between shapes of the loading and reverse loading hysteresis curves and consequently produce a closed loop with no ratchetting [10].…”

“…Stress analysis of a simple block is carried out as explained in [10] To capture the cyclic behavior, a single SOLID185 element is used with quarter symmetry boundary conditions and uniaxial displacement in the Y direction. Elastic properties for the special copper alloy (Cu-Cr-Zr-Ti) are Young's modulus of 110660 MPa and Poisson's ratio of 0.3. "…”

Cryogenic engines are commonly used in rockets for launching geosynchronous class satellites. The thrust chamber of cryogenic engines is generally of double walled construction. A high conductivity copper alloy is usually selected for the inner wall in regions of high heat flux and for other regions stainless steel is chosen. The failure of a thrust chamber is due to low cycle fatigue, creep of the inner wall, and thermal ratcheting. Present work deals with the study of different plasticity models for the cyclic stress analysis of a double walled cryogenic rocket engine thrust chamber. The work is done using ANSYS (Version 15) finite element code. Different plasticity models used for a simple cubic block showed that a combination of Chaboche's non linear kinematic hardening model in association with multilinear isotropic hardening and creep models is the best suited for cyclic stress analysis of the chamber. Cu-Cr-Zr-Ti alloy is investigated here as it is used in the inner wall of the thrust chamber. Material properties are taken from literature. A comparison of two dimensional (plane strain) and three dimensional cross section of thrust chamber is done. Cyclic life of the chamber is calculated from the cyclic stress-strain graph obtained from above analyses.
