... Abstract Oedometer tests were conducted on Gaomiaozi (GMZ01) bentonite to understand the swelling behavior under different stress and volume state conditions. The range of boundary conditions examined in the tests include swell-reloading (SR), constant volume (CV), and flexible load ring-based...

... for the proposed criterion (‘c’ and ‘d’) which have been estimated for used rock datasets by applying brittle-ductile transition as an initial boundary condition. The most proper brittle into ductile boundary, the confinement in which ∂ τ/ ∂ σ n =0 or in other words when ∂ σ 1 /∂ σ 3 =1, has been determined (σ 3...
