摘要: AbstractA multiphysics formulation for chloride diffusion in an RC beam with stress-induced damage quantifying the enhancement diffusivity due to is presented. An experimental investigation involving measurement of profile was conducted on beams damaged under applied flexural stress. Numerical simulation carried out using a two-dimensional finite-element approach incorporating stress, binding, and model. Concrete assumed be perfectly elastoplastic (Drucker-Prager) material steel as (von Mises) hardening. Drucker-Prager parameters, cohesion c, friction angle φ are obtained by calibrating numerical load-deflection (P-Δ) curve experimentally determined plot loaded flexure. Defining scalar index degradation elastic modulus expressed terms total strains, transport problem address...
