| Research Abstract |
An innovative strategy for inverse analysis using the nonlinear Kalman filter and the EM algorithm has been developed. Proposed numerical procedure can be applied to the identification of parameters of the elasto-plastic for geomaterials and defect within soil structure and ground deposit. Numerical analyses are applied to experimental and practical problems after examining through the synthetic measurements.
