“…The aim of the present work is to investigate the quasi-static and dynamic shear behavior of concrete under confined conditions. In previous experiments, concrete samples were either subjected to a small level of confinement [7] or a high level of confinement with a passive metallic cell [14]. In the last method, a strong change of confinement level occurs during the tests and constitutes a major drawback of this technique.…”

“…Another new experimental technique to study materials under shear loading was considered by [5]. This technique was then developed by [6][7][8]. The specimen is a short cylindrical sample with two cylindrical coaxial notches on the top and bottom faces leaving a cylindrical ligament.…”

“…Several PTS quasi‐static and dynamic experiments from the literature are gathered in Table 1. The Mode II fracture toughness of rocks was explored by Backers et al, [ 12,13 ] , Lee et al [ 14 ] and Luong [ 11 ] and more recently by Backers and Stephansson, [ 17 ] Li et al [ 22 ] and Yao et al [ 23 ] This technique was also used by Montenegro et al [ 15,16 ] to evaluate the mode II fracture energy of conventional concrete (maximum aggregate size 6 mm) as function of the hydrostatic pressure. Whereas no confining pressure was applied to the sample in the experiments from previous studies, [ 10,11,12 ] hydraulic pressure below or above the sample uniaxial compressive strength was considered for instance in the work from Backers et al [ 12,13 ] However, the hydraulic confinement used in PTS experiments presents several limitations and drawbacks: PTS experiments with hydraulic confinement require the use of triaxial presses that are quite expensive apparatus and difficult to operate.…”

“…The specimen is first subjected to a pure hydrostatic pressure whereas an axial load is added in a second step to create a shear fracturing of the ligament. This technique was more recently used by Montenegro et al [6] to evaluate the fracture energy of concrete as function of the hydrostatic pressure. More recently, a passive confining cell was used instead of hydraulic pressure to apply a confinement to the PTS specimen ( Fig.…”
