Effects of arbitrary holes/voids on crack growth using local mesh refinement adaptive XIGA

•The hole-crack interaction is investigated using an adaptive XIGA without re-meshing.•Adaptive analysis is conducted in terms of a stress recovery based error estimator.•Arbitrary shaped hole or crack is precisely described with the NURBS curve.•Effect of hole on crack growth is large as hole is near to crack.•The adaptive local refinement improves the accuracy at a low cost.
