USING BERNSTEIN POLYNOMIALS TO RECOVER ENGINEERING LOADS FROM STRAIN GAUGE DATA
( Departments of Applied and Computational Mathematics and Mechanical and Process Engineering, The University of Sheffield Sheffield S3 7RH )
An improved new method for the determination of interface pressures in contact zones between hard and soft components is described. The method uses Bernstein polynomials to represent the form of the interface pressure which is reconstructed by reverse processing of experimental strain-gauge measurements made in the hard component outside the contact zone.
