Generalized B-splines in non-polynomial space has been employed as
analysis tools for IGA. However, the previous models used in IGA are
not the unified mathematical representation of conics and polynomial
parametric curves/surfaces. In this paper, we propose a new isogeometric analysis framework called
NUAHT-IGA by using non-uniform algebraic hyperbolic trigonometric B-splines(NUAHT
B-splines for short) in the space spanned by
$\{\sin t,\cos t,\sinh t,\cosh t,1,t,\cdots,t^{n-5}\}$, which can be considered as an alternative to
NURBS model for unified representation of conics and polynomial
parametric curves/surfaces. The input CAD boundary
with conics and polynomial representation can be converted into NUAHT B-spline
form by matrix computation, and the solution space of NUAHT-IGA is
spanned by the quasi-B-spline basis defined in the algebraic
hyperbolic trigonometric space. Compared with
the NURBS-IGA method, the NUAHT-IGA method has several advantages such
as high accuracy, easy-to-compute derivatives and integrals due to the
non-rational form of NUAHT B-splines, and some remarkable
transcendental curves/surfaces such as the helix/helicoid, the cycloid and the catenary
can be involved in the unified framework. Several 2D and 3D examples
based on the heat conduction problem are presented to illustrate the
efficiency of the proposed method.
