A torispherical dome is the surface obtained from the intersection of a Spherical Cap with a tangent Torus, as illustrated above. The radius of the sphere is called the ``crown radius,'' and the radius of the torus is called the ``knuckle radius.'' Torispherical domes are used to construct pressure vessels.
