Fig. 18From: On the construction of approximation space to model discontinuities and cracks with linear and quadratic extended finite elementsAsymptotic behavior with Bernstein polynomials. Bernstein polynomials allow emphasizing once more that conditioning and accuracy are separated issues: the condition numbers of all three approximation spaces are almost the same, but there is a great difference in accuracy when “eps” \((\varepsilon )\) goes to zeroBack to article page
