Abstract

This work is dedicated to highlighting the effect of crack parallel normal stress on the resistance and failure mode of a notched concrete specimen subjected to 3-point bending. This test formulated by Bazant and co-workers is called the “Gap test” [1]. To do this we use the GM (Granular micromechanics) model behavior model, implemented in the Abaqus/Explicit code using the VUMAT user subroutine [2-3] [1] H T Nguyen, M Pathirage, G Cusatis, Z P Bažant. Appl. Mech. Jul 2020, 87(7): 071012. [2] M Ould Ouali, P Poorsolhjouy, L Placidi, A Misra. Constr. Build. Mat. 2021, 290, 123227. [3] A Misra, P Poorsolhjouy.
