hjli6,

Thanks. That looks very nice. I transfer this works to AutoCAD block, if you don't mind.
I wonder, Is that possible for you to upload the *.dxf or *.dwg file,
so that other people would follow the works.
CAD file would also make my job easy to calucate length of curve and area of sheet.
We are badly need the more specialists involve together.

============================================================


现公开诚聘如下高手：

模具板金高手 - 看看这个三角连接带如何开模，有啥讲究？
                          眼镜状面板 ball-bra 折弯如何计算？

编程优化高手 - 看看这个曲线长度和分割球面面积如何计算？下一步又如何优化？
                          我已上传几个 Mathmatica code 欢迎各位Code爱好者，共同探讨。

结构分析高手 - 看看这个球内外受力/应力-应变/强度/寿命 如何计算 ？


其他各类高手 - 看看.....

hjli6,

Please review my work. The essential curve length is clear.
I hope we have the same geometry so far.
I assume,
Ball radius= 1
Center point = 0.5
2D Curve radius = 0.4

The next job is to calucate the 3D Surface area. which is a little bit challenge.
I made the experience on 2D area, Anyone want to try 3D now ?
