2.2 Test Apparatus. The experiments were carried out using a triaxial test apparatus, with a frame stiffness of 4 × 10 8 N/m, which can apply the maximum axial load of 1000 kN and 60 MPa of confining pressure, respectively. The test apparatus provides two LVDT micrometres and a circle-spring extensometer to measure the axial and …

This study concerns the identification of concrete behaviour under severe triaxial loadings (rock falls, explosions, ballistic impacts). In order to reproduce high stress levels with well controlled loading paths, static tests are carried out on concrete samples by means of a very high capacity triaxial press (stress levels of the order of the GigaPascal).
