ABSTRACT

ABSTRACT: This paper is concerned with the steady flow of Bingham viscoplastic materials in rock fractures. Bingham materials are such that below a critical shear stress they act as a solid and no flow occurs. Once the critical stress has been exceeded, they behave as a fluid and flow occurs. The laminar flow of Bingham materials can be described by a modified cubic law where the fracture transmissivity is a non-linear function of the gradient. Using an analytical solution previously proposed by the author and based on the integral transform method, an iterative procedure is presented to predict the steady flow of Bingham viscoplastic materials in rectangular fractures with variable aperture and surface roughness.
