“…The use of linearly varying fiber angle per bay, for stiffened plates, has also been investigated, and again it has been shown that varying the fiber angles leads to better performance [7,8]. Direct parametrisation of the tow paths using Lagrangian polynomials [9,10,11] Lobatto-Legendre polynomials [12,13], Bezier curves [14,15,16], splines [17,18], B-splines surfaces [19] and NURBS (Non-Uniform Rational B-Splines) [20] have also been used. Constant curvature paths have been extensively applied for flat panels and for cylindrical and conical shells [21,22,23,24,25], as the curvature constraint evaluation is simplified.…”
