Method and program for the interpolation of experimental results of determining the mechanical properties of mineral composites for modern machine–tools

摘要

The paper presents a method of interpolating bifactorial experimental data with the aim of extending the results over the entire domain defined by the independent variables. This approach can be used in determining the optimum mineral casting mixes for a given application. Mechanical properties such as stiffness, ultimate tensile strength, yield strength and Poisson's coefficient can be improved.The paper describes the implementation of a radial basis function (RBF) algorithm in a MATLAB program for the interpolation of data, plotting of the results and the identification of the maximum dependent variable and the independent variables that correspond to it. It also provides the source code for the program along with explanations regarding its use. RBF interpolations can be used successfully in response surface methodology to generate approximations of the studied variables based on the experimental results. The program can be extended to work on any number of input and output variables.
