Overview

Analysis shows ratcheting in steel alloys at varying temperatures, suggesting complex interactions impact material strength.

Key Points

  • Ratcheting was lower at elevated temperatures, with dynamic strain aging influencing material response.
  • The stress-strain hysteresis loops provided crucial analytical data for assessing ratcheting behavior.
  • Finite element analysis evaluated backstress evolution employing the Chaboche hardening model developed in ANSYS software.
  • The results demonstrated good agreement with experimental data, confirming the effectiveness of both the A-V framework and FEA method.
