Development of a Photoelastic Experimental System for Measuring Stress Chains in Granular Systems [PDF]

open access: yes, 2001
A measurement system of stress distribution in granular systems were developed using photoelasticity. Stress transmission among two types of acrylic resin cylinders with diameters of 8 mm or 10 mm and a height of 10 mm were measured by using the stress ...
