| Outline of Final Research Achievements |
Developable surfaces are obtained by optimizing the control points of Bezier curves defining the directing curves of the ruled surface.It has been shown that the free-form shells modeled by developable surfaces can be optimized considering various mechanical properties. An optimization method has also been developed for gridshells generated by applying bending deformation to plane grids of beams. Furthermore, relation between the strain and Gaussian curvature has been analytically derived, and optimization problem has been formulated to find the range of Gaussian curvature and strains of a quadratic surface.
