Abstract: An internal deformation analysis experimental device and method for a three-dimensional particle material, including an internal deformation analysis experimental device for a three-dimensional particle material includes: several particles, which are transparent solids; an infiltration liquid, the refractive index of the particles being the same as that of the infiltration liquid; a container, configured to accommodate the particles and the infiltration liquid; a laser device, arranged on an outer side of the container, the infiltration liquid being able to generate fluorescent light when laser emitted by the laser device irradiates the infiltration liquid; a recording apparatus, arranged on the outer side of the container and configured to collect and acquire a sequential image of the particles; and a computing terminal, the recording apparatus sending the acquired sequential image of the particles to the computing terminal, and the computing terminal constructing a three-dimensional particle system through the sequential image of the particles.
