• Abstract:
  A newly developed optical tracker measuring system was used for observing the dynamic displacement vector at points on the periphery of a compacted triaxial test specimen of granular material subjected to rapid, repetitive loading. The material was a crushed limestone of the type used in highway pavements. The displacement data were converted to components of normal strain, and a mathematical model was developed that expressed each strain component as a function of the applied stresses. The model contained a variable modulus dependent upon both the lateral pressure applied to the specimen and its stress history.
