A natural design process called form finding, inspired by the natural world, has been taken to the next level by University of Warwick Emeritus Professor Wanda Lewis. This process enables the the design of rigid structures that follow a strong natural form, which due to sustenance by a pure compression or tension force have no bending stress.
Lewis studies forms and shapes in nature for 25 years developing thoughts on this process that would help to create structures with enhanced safety, long durability, and no need form restructuring or repair:
A piece of fabric is suspended, and allowed to relax into its natural, gravitational, minimum energy shape; then that shape is frozen into a rigid object and inverted. She finds the coordinates of this shape through computation by simulating the gravitational forces applied to the structure. This produces a shape (a natural form) that can withstand the load with ease.
