Scaled Experimental Modeling
Scaled experimental model is a powerful tool to better understand the geometry and kinematics of natural geologic structures. These physical analog models also allow modelers to explore how different variables (e.g., strength of rocks, strain rate, deformation direction, etc.) affect structural patterns that are present in nature.
My current modeling research include simulation of salt structures and oblique shortening deformation. In these models, I use various modeling materials such as dry sand/wet clay and silicone polymer to simulate non-evaporitic rocks and salt rocks, respectively. My research goal is to better understand the deformation behavior of salt deposits and how it affects the formation of salt structures.
