Strain-Based Theoretical Fatigue Damage Model of Concrete Material
https://orcid.org/http://orcid.org/0000-0002-6061-1124
Based on the modulus mortification rule of continuum internal variable theory of thermodynamics connected to concrete materials under frazzle loading, a simple, reliable, better and computational efficient theoretical fatigue damage model due to formation of microvoids, microcracks, microdefects and fractal is proposed. The prescribed new theory is linked with strain-based approach where “strain” is the main domain and is capable for prediction of fatigue life of concrete as well as cementitious and brittle material. Investigational data from fatigue test were employed to validate the model, and results show that the model can describe the fatigue damage progression of concrete materials under different frazzle loadings by verifying the predicted fatigue life. Mortification of elastic modulus, damage enlargement corresponding to the normalized life, degradation of stress level from elastic to plastic and its accumulation subjected to variable frazzle loading including its verifications are well discussed.
