“…In the region of the CSC where deformations localize in a single crack (opening–sliding mixed‐mode behavior), it is considered that the shear‐transfer capacity is governed by the residual tensile strength and the aggregate interlock stresses, leading to the following normal ( σ agg ) and shear ( τ agg ) interlocking stresses as a function of the crack opening ( w T ) and sliding (Δ T ) (according to Cavagnis et al): where σ fct refers to the residual tensile strength, τ agg, 0 and σ agg, 0 are the shear and normal stresses due to aggregate interlocking engagement. According to Hordijk, the residual tensile strength can be calculated as where f ct refers to the tensile strength of concrete, w c is the crack opening corresponding to a zero tensile stress, and t 1 = 3 and t 2 = 6.93 are constants 59 .…”
