摘      要：This paper presents an isogeometric boundary element method(IGABEM)for transient heat conduction *** Non-Uniform Rational B-spline(NURBS)basis functions,which are used to construct the geometry of the structures,are employed to discretize the physical unknowns in the boundary integral formulations of the governing *** extraction technique is employed to accelerate the evaluation of NURBS basis *** adopt a radial integration method to address the additional domain *** numerical examples demonstrate the advantage of IGABEM in dimension reduction and the seamless connection between CAD and numerical analysis.
