“…Such a direct approach to composite characterization was developed by Grediac et al [10,11], who adopted a methodology requiring accurate mode shape measurements. Hanss et al [12] combined their characterization methodology with an assessment of the sensitivity of vibration modes and natural frequencies to various material parameters.…”

The proposed characterization method is based on the knowledge of free vibration characteristics of plate specimens. Effective laminate properties are estimated through minimization of the error between known and predicted natural frequencies. Metamodeling is used for approximating the relationship between the material properties and the corresponding natural frequencies. This results in an economical characterization process, applicable to a large number of specimens of various shapes and dimensions. The proposed strategy is first tested on a range of hypothetical composite materials with numerically simulated test results, then applied to reliable published experimental data. It is thus shown to have the potential of a fast and accurate, in-situ characterization tool.

In this paper, the free transverse vibrations of rectangular orthotropic plates with completely free boundary conditions are considered. Some methodologies for calculating the eigenfrequencies and eigenmodes, based on the classical thin plate theory are presented in a comparative overview. The advantages and disadvantages of these methodologies are discussed for an orthotropic plate application with specific material and geometric properties.

Interval analysis is a new uncertainty analysis method for engineering structures. In this paper, a new sensitivity analysis method is presented by introducing interval analysis which can expand applications of the interval analysis method. The interval analysis process of sensitivity factor matrix of soil parameters is given. A method of parameter intervals and decision-making target intervals is given according to the interval analysis method. With FEM, secondary developments are done for Marc and the Duncan-Chang nonlinear elastic model. Mutual transfer between FORTRAN and Marc is implemented.With practial examples, rationality and feasibility are validated. Comparison is made with some published results.
