An efficient piezoelectric sandwich beam finite element is presented here. It employs the coupled polynomial field interpolation scheme for field variables which incorporates electromechanical ...
All the zeros x2m,i, i = 1(1)2m, of the Chebyshev polynomials T2m(x), m = 0(1)n, are found recursively just by taking n2n-1 real square roots. For interpolation or integration of ƒ(x), given ƒ(x2m,i), ...
Abstract: Base on the Lagrange interpolation polynomial algorithm, the error analysis is discussed in this paper. Firstly, we derive the Lagrange interpolation ...
