Photoelastic Granular Mechanics
Full-field particle stress measurement, force-chain evolution, jamming, unjamming, cyclic response, and liquefaction-related mechanisms.
Photoelastic Granular Mechanics Laboratory · ECJTU
Seeing forces inside granular materials.
We investigate how granular materials carry load, reorganize, flow, and interact with engineering systems through photoelastic experiments, advanced imaging, and discrete-element modeling.
Research
From particle-scale force transmission to engineering-scale behavior.
Our work connects fundamental granular mechanics with quantitative experiments, computation, and engineering applications.
Granular Materials & Geomechanics
Particle morphology, critical-state behavior, fabric evolution, contact mechanics, and discrete-element modeling of granular soils.
Granular–Equipment Interaction
Excavation, wear, mining and construction equipment, particle–structure interaction, and mechanics-informed productivity.
Experimental Platform
A dedicated platform for full-field granular stress imaging.
Our custom experimental platform integrates polarization optics, controllable motion, imaging, and mechanical testing to support quantitative photoelastic measurements in granular systems.
Full-field imaging
Controlled polarization
Particle-scale stress analysis
Granular loading experiments
Photoelasticity
Stress becomes visible.
Polarized-light imaging converts otherwise invisible stress information into measurable fringe patterns.
