In the fatigue behaviour of aluminium/aramid fibre core in four-point flexural test, the fracture pattern (Figure 12.14) formation in both W and L configuration are the same and is not affected by the fatigue failure. Both W and L sandwich structure break down in shear with a crack propagating through the core thickness (A. Abbadi, et al. 2010).

The four-point flexural test is frequently used to assess ECC's flexural toughness. Different toughness indices were introduced by ASTM C1018 to estimate the flexural behavior, degree of flexibility, and amount of energy absorption of fiber-reinforced concrete. Flexural toughness is defined by the indices I5, I10, I20 (explicitly stated in the code), I30, and I40 (implicitly expressed in the code). Each of these represents the ratio of the area under the load-displacement curve up to specified displacements of 3δ, 5.5δ, 10.5δ, 15.5δ, and 20.5δ, respectively, to that of the displacement corresponding to the cracking moment represented by δ. Moreover, the area below the load-displacement diagram was used to determine the energy absorption.
Instantaneous and long-term performance of foamed concrete slabs
Published in European Journal of Environmental and Civil Engineering, 2022
Even though testing six slabs under three-point flexural procedure and six slabs under four-point flexural test was for flexural strength investigation, their results can be used in this paper to calculate their flexure modulus of elasticity as discussed later in this paper.
