英文摘要：
This paper presents a general numerical model facilitating to the sensitivity analysis for solving the inverse couple stress problem. A FE based numerical model is developed to formulate direct problem, and direct and adjoint methods are used to conduct on the sensitivity analysis. Gauss-Newton technique is employed to identify unknown constitutive parameters with the consideration of material inhomogeneity. The effects of initial guess, number of sample points and data noise on the solutions are investigated, and satisfactory results are exhibited in the numerical verification.
