Overview

Randomized trial evaluates new elastoplastic model simulating stiffness degradation in concrete, suggesting enhanced predictive accuracy.

Key Points

  • This study aims to develop a new elastoplasticity model to simulate the nonlinear behavior of high-performance concrete.
  • Developed an elastoplastic model based on the extended Prandtl–Reuss formulation.
  • Introduced a generalized invariant for decoupling tension-compression asymmetry.
  • Validated model predictions against multiple experimental datasets.
  • The model captured asymmetric hardening-softening response under monotonic loading accurately.
  • Demonstrated path-dependent stiffness degradation during unloading without explicit damage variables.
  • Achieved high predictive accuracy with limited interpretative parameters.
