A lab that explores reliability assessment and analysis technologies for ships and offshore structures.
AboutAbout the lab
Estimating risk to inform structural design
The Structural Information Systems Lab conducts research in naval architecture and ocean engineering, structural mechanics, and computational mechanics.
Recently, it has focused in particular on life-cycle risk assessment and structural reliability assessment of ships and offshore structures.
In computational mechanics, it studies CAE technologies such as mesh generation and the finite element method.
On the lab's website, it is introduced under the name "Kawamura Lab."
Key terms
- Life-cycle cost
- The sum of the various costs over a structure's entire life, such as construction cost, maintenance cost, and accident risk.
- Probability of failure
- The probability that a structure fails. The higher it is, the lower the strength, and the less needs to be spent on materials.
- Finite element method
- An analysis method that divides the object of analysis into a fine mesh and performs calculations on it. It is used in many fields.
- Mesh
- A collection of elements into which the object of analysis is finely divided for finite element analysis.
ResearchResearch themes
The lab conducts research on risk assessment and structural reliability assessment of ships and offshore structures, as well as CAE technologies such as mesh generation and the finite element method. Through its research, the lab aims to foster students' creativity and independence and to propose new concepts and methods that are useful to society.
*Illustrative imageRisk-Based Structural Design and Maintenance of Ships
The lab studies methods for planning structural design and maintenance that minimize life-cycle cost. The work is based on the idea that the higher the probability of failure, the lower the construction cost, and the higher the maintenance cost and accident risk.
*Illustrative imageCAE Technology for Automatic Mesh Generation
In finite element analysis, the effort required to divide the object of analysis into a fine mesh is a major problem. The lab studies algorithms that automatically generate a mesh when a shape is given, and creates hexahedral meshes using geometry recognition and sweeping.
