We have been investigating the following to ensure the safety of passengers, crew, and cargo, and to improve structural strength while maintaining economic efficiency:
  1. Crashworthiness of vehicles
    Damage prediction techniques in collisions using numerical simulation
    Development of new energy absorption elements (hybrid structures) to reduce damage
  2. Buckling and ultimate strength of plate and shell structures
    Buckling and ultimate strength of spheres, cylinders, and ellipsoidal spheres with imperfections
    Evaluation of residual strength after vehicle collisions
  3. Development of new lightweight and low cost structural members with sufficient strength
    Development of hybrid structures (alternatives to stiffened panels)
  4. Development of new numerical simulation techniques, such as the structural optimization technique, distinct element method, and fluid-structure coupling analysis
    Ore pressure estimations that consider the coupling effects on particle behavior and structural deformation using the distinct element method and FEM
    Structural optimization procedures using genetic algorithms and neural networks
    Coupling analysis of fluid and structure using the ALE technique
