Abstract

This paper presents a novel approach to the integration of biological inspiration into topological optimisation through the specification of input parameters derived from nature. The aim is to create biomimetic designs that may incorporate the multifunctionality inherent in natural systems. The presented methodology for modelling bioinspired structures using topological optimisation provides critical insights into translating natural forms and their load-bearing characteristics into topological optimisation design parameters (design space, boundary conditions, and loads). The proposed BioTop method is a structured framework that guides designers through a design-to-biology approach for conducting truly bioinspired topological optimisation by systematically defining the required inputs. An illustrative case study demonstrates the practical application of the BioTop method and its capacity to create bioinspired topologically optimised structures. While acknowledging current simplifications, this research lays a foundation for future research in bioinspired design by providing a systematic method for using nature as an informed input source for the standard topological optimisation software.
