“…The major goal is to achieve a smooth transition from geometric design to analysis using computer-aided design (CAD) basis functions, e.g., non-uniform rational B-spline (NURBS) basis functions, for both processes. In the last decades, IGA has experienced a rapid evolution with many engineering applications, for example, vibration analysis [1,2], structural analysis [3][4][5][6][7][8], damage and fracture problems [9,10], optimization [11,12]. In particular, dynamic analysis of beam structures using the IGA approach has been studied in recent years.…”
