Paper Number: ARMA-2000-0785
... 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...
