Evaluation of Static and Dynamic Contact Stresses in Simulated Granular Particles Using Strain Gages



The application of strain gages for the determination of static and dynamic contact loads in granular perticles is demonstrated. For experimental convenience, the grandar particles are simulated by circular disks fabricated from Homalite-100, a brittle polyester material. Stress field equations in the vicinity of the contact points are carefully evaluated to optimize the relative position of strain gages. The results obtained from strain gages were compared with those obtained using the optical technique of photoelasticity for both static and dynamic problems. Finally, as an example, strain gages are used to study wave propagation in a single chain assembly of disks.
