A simple, efficient and accurate Bézier extraction based T-spline XIGA for crack simulations

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...
