Full Characterization of the Work-Hardening Behavior of Metals: An Accurate and Explicit Approach

Full Characterization of the Work-Hardening Behavior of Metals: An Accurate and Explicit Approach A new approach is proposed to characterize the work-hardening behavior of metals based on the stress–strain data from uniaxial extension testing. With this new approach, the yield strength as a function of the plastic work can be determined by directly fitting a well-chosen single-variable shape function to any given uniaxial data from the initial yielding up to the strength limit, in an explicit sense with no need to carry out the usual tedious trial-and-error procedures in treating nonlinear elastoplastic rate equations toward identifying numerous unknown parameters. Numerical examples show that the simulation results with the new approach are in accurate agreement with the test data. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Acta Mechanica Solida Sinica" Springer Journals

Abstract

A new approach is proposed to characterize the work-hardening behavior of metals based on the stress–strain data from uniaxial extension testing. With this new approach, the yield strength as a function of the plastic work can be determined by directly fitting a well-chosen single-variable shape function to any given uniaxial data from the initial yielding up to the strength limit, in an explicit sense with no need to carry out the usual tedious trial-and-error procedures in treating nonlinear elastoplastic rate equations toward identifying numerous unknown parameters. Numerical examples show that the simulation results with the new approach are in accurate agreement with the test data.
