Computational modelling of failure mechanisms in reinforced concrete structures [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2010 A modelling approach for macroscopic reinforced concrete (RC) structures and structural elements under static loading conditions is presented. It uses the embedded modelling technique to separately account for concrete volumes and single longitudinal ...

Failure and Deformation of Sand in Torsional Shear
Soils and Foundations, 1986 ABSTRACT The deformation and strength characteristics of sand was studied by means of the torsional shear tests on hollow cylindrical samples with a height of 20 cm, an outer radius of 5 cm and an inner radius of 3 cm. It was found that in order to obtain accurate results it is essential both to very precisely measure the axial load, the torque and ...

Finite Element Simulations of Dynamic Shear Fracture of Hollow Shear Pins
International Journal of Aerospace Engineering, 2021 The shear pin structure is widely used in aeronautics and astronautics structures to deal with emergency structure separation problems. The shear pin design has a strict restriction on the precise failure load and definite failure mode. Previous research

Dilatancy stabilises shear failure in rock [PDF]
Earth and Planetary Science Letters, 2021 <p>Failure and fault slip in crystalline rocks is associated with dilation. When pore fluids are present and drainage is insufficient, dilation leads to pore pressure drops, which in turn lead to strengthening of the material. We conducted laboratory rock fracture experiments with direct in-situ fluid pressure measurements which ...
