A developable surface is one that can be made from a flat sheet without any in-plane strains. 可展曲面是一个可以由平板在不发生任何面内应变的条件下弯成的曲面。
The results of the calculating examples show that this method is accurate when the curved surface is developable, and has high precision when the curved surface is undevelopable. 算例表明,本方法对可展曲面的展平是精确的,对不可展曲面的展平精度很高。
