Application of NURBS in the Fracture Mechanics Framework to Study the Stress Intensity Factor

In this investigation, we successfully employed the Non-Uniform Rational B-spline (NURBS) to study fracture mechanics. NURBS functions are very popular in design field (CAD model) and it is used as an alternative Lagrange interpolation polynomials. The extended isogeometric analysis based on basis function evaluate stress intensity factors (SIFs) order control crack propagation. For various lengths, SIFs were calculated validate accuracy of technique. results obtained good agreement with available techniques CFEM, X-FEM.
