Data-driven Computing in Elasticity via Chebyshev Approximation

This paper proposes a data-driven approach for computing elasticity by meansof a non-parametric regression approach rather than an optimization approach.The Chebyshev approximation is utilized for tackling the material data-setsnon-linearity of the elasticity. Also, additional efforts have been taken tocompare the results with several other state-of-the-art methodologies.
