Good afternoon everyone,<\/p>\n

 <\/p>\n

I’m trying to simulate a displacement of a radial band to compress radially a semisphere. This band is modeled with an internal radius equal to the external radius of the eye but it has really a lesser radius so the idea is to model the pressure that the band apply to the sphere as a result of trying to recover its real radius. <\/p>\n

I have created a cylindrical coordinate system and I have modeled firstly as a displacement of the internal surface of the band that is in contact with the external surface of the sphere but it doesn’t get a result. Secondly, I have calculated the pressure it apply as p = E * (R – r )\/ r where E is the young modulus of the band and R y r are the external radius of the sphere and the real radius of the band (that it wants to recover). The problem in this second analysys is that it gets a excessive displacement compressing the sphere in a irreal manner.<\/p>\n
