Abstract

Abstract

To investigate the effect of prestrain on the mechanical properties of TA2, room temperature tensile tests were conducted on the TA2 original material and specimens with the prestrains of 10%, 20%, and 30%. Based on the influence of prestrain on the mechanical properties of TA2, prestrain variables were introduced to modify the Hollomon model, Ludwik model, and Swift model to predict the mechanical behavior of prestrained TA2. The results show that with the increase of prestrain, the yield strength of TA2 increases significantly, the tensile strength slightly increases, and the elongation after fracture, strength plastic product, and strain hardening indexes decrease. Prestrain enhances the strength of TA2 by consuming plastic properties, and the plastic strain energy density and fracture strain energy density of TA2 decrease significantly with the increase of prestrain. The average correlation coefficients between the predicted results of each modified model and the experimental values are 0.9862, 0.9994, and 0.9744, with the maximum prediction errors of 6.34%, 8.33%, and 16.42%, respectively. Among them, the Hollomon model has a simplified structure and good prediction accuracy, making it the best choice to describe the effect of prestrain on the mechanical behavior of TA2.
