Abstract: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.
