In the present work, a simple, efficient and accurate Bézier extraction based T-spline XIGA
(BEBT-XIGA) has been proposed for the crack simulations. Bézier extraction maps T-spline
basis functions over the element in the forms of Bernstein polynomial basis defined over the
Bézier element. T-spline basis functions over the element can be written as linear
combination of Bernstein polynomials basis. Bézier extraction approach generates an
element extraction operator and Bézier element for fracture analysis. A crack is modelled in …
