Research Themes

A study on patient-specific modeling and mechanical analysis of bone

A study on patient-specific modeling and mechanical analysis of bone The patient-specific individual analysis is ideal for clinical application of biomechanical analysis of bone, because the shape of bone and the tissue morphology is various depending on the person. In the study, the mechanical analysis model by whom the shape of bone and the tissue morphology are faithful to the patient is made based on the medical images such as CT and MRI, the loading condition corresponding to the patient state is given to it furthermore, and it aims at the establishment of the mechanics analysis technique to obtain a useful result for clinical. (Left figure shows a color contour map display against three osteoporosis patients as stress-strength ratio obtained by the analysis, when the load of 100Kgf apply to the first lumbar vertebra. The spine fracture risk of each patient is quantitatively appreciable.)

A study on biomechanics of musculoskeletal system on spine

A study on biomechanics of musculoskeletal system on spine Human came to have various mechanical problems in the spine by standing upright. Although the structure, that a long and slender spine column supports a heavy head, is unstable while standing upright, the posture is kept by working the muscle and the ligament around the spine. The bone and the muscle cooperated as a musculoskeletal system support the load of the upper part of the body. However, once the mechanical balance of the musculoskeletal system gets worse by sick or aging, the influence appears as back pain and various spondylosises. In the study, it has aimed that the mechanical factor of the spine trouble is searched by analyzing the mechanics of the musculoskeletal system of the spine, and the treatment method is examined. (Left figure shows the research to which a mechanical influence of the posture change by the compression fracture of vertebrae is evaluated by the musculoskeletal simulation of the spine. )

A study on plant biomechanics

A study on plant biomechanics The plant has been evolved the material property and the structure of the organization to adapt to surrounding mechanical environment, because it doesn't have the motor organ like the muscle of animal. Ingenious adaptation of their material and structures to loading condition is observed by investigation of mechanical property and strength of the plant. The method of mechanical adaptation of the plant gives us the new paradigm to the strength design of the mechanical structure. In this research, it has aimed to analyze the plant mechanically, and to obtain the new idea of mechanical design through the investigation of the adaptability and the optimality of the plant. (Left figure shows the example of researching the mechanism of a high-speed movement of the plant fruits that burst and scatter the seed. )
