... Load (MTS machine) Fig. 4. Loading Frame and Experiment Set-up 3. OBSERVATIONS Photoelasticity has been used in engineering to display and measure full-field stresses and strains in materials under static or dynamic loading [20-22]. As the shear stress applied to the specimen increases, photoelastic...

... 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...
