Mechanical Behaviours of Geomaterials


Laboratory test

We have developed the advanced laboratory testing apparatus for mechanical behaviours at different strain level subjected to various loading conditions.


Micro-scale measurement

We also evaluate the granular materials at across scales including gradation, particle shape, and surface roughness.  


Numerical simulation

Besides the physical tests, we also have quite advanced numerical code to seek for the mechanisms behind.
