Solve various problems related to earthquakes by taking advangate of applied mechanics, mathematics and computer sciences.
Full computation of earthquake hazards and disasters
Examples of integrated earthquake simulation
Stress inversion method: find equilibrating stress using measured strain and partial information on stress-strain relation
Elasticity inversion method: find local elasticity using densely measured displacement
Development of sensing / simulation methods for civil infrastructures
Development of numerical simulation tool for analysis of failure phenomena
Numerical analysis method for failure phenomena, FEM-beta, is under development. This method employs particle discretization for field variables. Rigorous formulation and easy treatment of failure with reasonable computational cost enable us to perform monte-carlo simulation of structure collapse.
Stress field tomography based on 3D photoelasticity
Non-destructive, no-contact measuring method for 3D stress field in materials has been developed. This method is based on 3D photoelastic measurement and nonlinear inverse analysis method. Technically, this method can be regarded as a tensor field tomography with equilibrium constraint.
