Abstract:
A novel method was developed for sensitivity analysis and elasto-plastic parameter identification. Using complex variable differential method, partial differential of an implicit function is reduced to function numerical calculation in complex domain, and parameter sensitivity is computed more accurately and efficiently than using the traditional finite difference method. An inverse process method via complex domain displacement analysis was established for elasto-plastic parameter identification in geotechnical engineering. The elastic modulus, Poisson ratio, cohesion and friction angle were identified accurately. With numerical verification, the developed method is efficient and reliable for elasto-plastic parameter identification and nonlinear parametric inversing analysis.
