The lab predicts the behavior of soil and rock using theory and computation built on as few assumptions as possible.
AboutAbout the lab
Describing complex ground with few assumptions.
The Computational Science Lab studies the behavior of geomaterials such as soil and rock, predicting it with theory and numerical computation.
Many civil engineering problems are multiphysics problems, in which the mechanics of solids, liquids, and gases and the transport of matter and heat occur at the same time.
The lab covers everything from building models that describe material properties, to large-scale computation on supercomputers, to applying them to real problems.
It also carries out laboratory tests and field measurements to validate the models.
Key terms
- Multiphysics problem
- A problem in which multiple phenomena, such as the transmission of forces, the movement of water and heat, and chemical changes, occur and interact at the same time
- Granular material
- A material made up of many particles, such as sand and gravel
- Occam's razor
- The principle that more assumptions than necessary should not be made to explain a phenomenon
ResearchResearch themes
The lab works broadly on multiphysics problems in civil engineering, from fundamental theory to high-accuracy, large-scale numerical computation techniques for solving real problems. Its theme is to describe phenomena that look complex using a combination of as few and as simple assumptions as possible.
*Illustrative imageModeling Geomaterials
Ground is a material in which solids, liquids, and gases are mixed. Based on the principle of Occam's razor, the lab develops models that rationally represent how forces act on the ground and how water moves through it, using as few assumptions as possible.
*Illustrative imageParticle Behavior and Overall Response
Ground is a granular material made up of many particles. By combining high-precision laboratory experiments with analysis techniques for granular materials, the lab seeks to clarify how fine-scale interactions between particles determine the behavior of the ground as a whole.
*Illustrative imageFrom Experience to Theory
The lab aims to re-explain, through theory, ground phenomena that have so far been explained only empirically. Focusing on tunnels and embankments, it develops techniques to predict how fragile rock weathers and how stable earth structures remain over long periods.
*Illustrative imageApplications to Soil Contamination and Cultural Heritage
To predict with high accuracy how soil becomes contaminated by oil and heavy metals, the lab has developed everything consistently, from building physical models to numerical analysis techniques. In collaboration with researchers in other fields, it also works to clarify the mechanisms by which cultural heritage deteriorate.
