We consider the incrementaL response of a deformed aggregate of spherical particles that interact through elastic, frictional contacts. We show that when the principal axes of the incrementai strain do not coincide with the principal axes of the existing strain, the average rotation of the particles is not the same as the average rotation of the aggregate. We incorporate this difference when calculating the effective moduli of the deformed aggregate.

Abstract
We consider the incrementaL response of a deformed aggregate of spherical particles that interact through elastic, frictional contacts. We show that when the principal axes of the incrementai strain do not coincide with the principal axes of the existing strain, the average rotation of the particles is not the same as the average rotation of the aggregate. We incorporate this difference when calculating the effective moduli of the deformed aggregate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
