Overview

Randomized trial evaluates ratcheting in stainless steel under loading cycles, suggesting implications for material failure studies.

Key Points

  • This study aims to evaluate the ratcheting behavior of 304 stainless steel samples under various loading conditions with hold times.
  • Samples of SS304 were subjected to asymmetric loading cycles with holding periods.
  • The combined A-V kinematic and L-Z isotropic hardening rules were used to model the materials.
  • Nonlinear and time-dependent functions were introduced to incorporate static recovery terms.
  • The static recovery phenomenon enhanced plastic deformation in the samples tested with hold times.
  • Increased hold times resulted in reduced cycles to material failure, indicating higher susceptibility to ratcheting.
  • The study successfully predicted material behavior under specified loading and dwell conditions.
