Reliability Assessment Lab
Machine-translated · View original
The lab explores new manufacturing technologies centered on composite materials and reliability.

AboutAbout the lab
Creating new manufacturing technologies through cross-disciplinary collaboration
The Reliability Assessment Lab centers on composite materials engineering, reliability engineering, and engineering education, and studies manufacturing in a wide range of fields, including biomedical engineering, energy and the environment, electronics, and disaster prevention.
Through interdisciplinary integration and industry-academia collaboration, the lab carries out research and development of simulation technologies for creating new technologies, as well as of the new technologies themselves.
On the lab's website, it is introduced under the name "Kurashiki Lab." In the graduate school, it is also in charge of the Technology Design chair of the Department of Business Engineering.
Fourth-year undergraduates are assigned to the lab only from the Production Science Course of the Department of Applied Science and Engineering.
Key terms
- Advanced fiber-reinforced composite materials
- Materials with high strength, high stiffness, and light weight. They have complex shapes in which multiple fiber bundles are interlaced
- Image-based analysis
- A method that builds numerical analysis models of bone from CT images and evaluates the strength and stiffness of artificial joints
- Risk assessment
- Evaluation of the effects of a disaster that takes into account the amount of damage to nearby residents and plant equipment

ResearchResearch themes
The lab carries out research and development on manufacturing in a wide range of fields, including materials, biomedical engineering, energy and the environment, electronics, and disaster prevention and risk, with interdisciplinary collaboration as its keyword. It works on simulation technologies for generating new technologies, and on the creation of new technologies themselves.
*Illustrative imageEvaluating the mechanical properties of advanced composites
Advanced fiber-reinforced composite materials are expected to be used in aerospace as well as in fuel-powered automobiles and wind turbine blades. To create reinforcing fiber structures suited to required purposes, the lab develops simulations that evaluate mechanical properties, along with new experimental techniques.
*Illustrative imageImage-based biological simulation
Against the background of a growing number of patients with osteoporosis, the lab works on developing custom-made artificial joints that fit each patient's skeletal shape precisely. It studies image-based analysis, which builds numerical analysis models of bone from CT images and goes on to the shape design of artificial joints and the evaluation of their strength and stiffness.
*Illustrative imageDisaster simulation for large-scale earthquakes in major cities
To reduce human and material damage when a major earthquake strikes the Tokyo metropolitan area or the Keihanshin region, the lab develops simulations that support estimating damage conditions and optimizing response. Focusing on disasters at chemical plants, it uses computers to grasp the process from occurrence through spread to the effects of disaster prevention, and extends this to risk assessment that takes the amount of damage into account.
