Abstract
Conventional engineering design approach is to solve a structure for its strength. On the other hand, natural shapes and structures are more free-form, using stiffness and flexibility whenever and wherever necessary. Form-finding approaches for structural design draws inspiration from different trades of nature. In this work, an attempt is made to generate free-form structures using biological forms like growth of a plant. Generative design strategy within constrained design space was developed, and behavior of such solutions under different loading are discussed. Thus a structure is evolved (and adapted) via bottom-up approach, and not constructed (and optimized) as top-down process.
Selected examples show the robustness and flexibility of the structures depending on the application. The testing examples also enable the designer to improve the problem statement along with the solution sets. A smooth back and forth parametric modeling process facilitates a smooth interaction between design and analysis, which is essential in form-finding approaches. A free-form self-organized shape would enable the algorithm to directly interact with printing techniques, easing manufacturing.
