GB/T 47244-2026Heterogeneous biomimetic structures - Design, manufacture and optimization - Methodology (English PDF)

3.1

In biomimetic structural materials or components, the smallest structural unit that can indicate its structural, morphological, and compositional characteristics.

3.2

Within a certain scale range, local regions of a material exhibit diverse physical properties, chemical composition, mechanical structure, and mechanical properties.

The structure of attributes.

Note. Composite materials with a periodic distribution of reinforcing phases (such as fiber/particle reinforcement) belong to a special type of heterostructure.

3.3

By mimicking the heterogeneous distribution of biological structures in terms of morphology, mechanics, or materials, we can design and fabricate substances with certain superior functions or properties.

Artificial structures.

3.4 Material optimization

Guided by the target function, a systematic approach is adopted to match material properties with the requirements of biomimetic structures by adjusting material composition and microstructure.

method.

Note. Material properties include, but are not limited to, specific indicators such as strength, stiffness, toughness, and corrosion resistance.

3.5

Based on the topological characteristics and load transfer laws of biological prototypes, parametric modeling, finite element simulation, topology optimization, or machine learning are used to calculate...

Methods are the process of iteratively improving micro/meso/macro structural parameters such as geometric shape, structural distribution, and connection method.
