Summary

With millions of years’ evolution, biologies including plants and animals have possessed perfect and exquisite biological systems, with highly developed complexity and specialty. Based on the spirit “learn from nature”, people have got comprehensive understandings of the special functions of biology, and many new devices and materials have been invented by bionic design. As a consequence, Bionics has a wide spectrum of applications in many areas, such as aerospace, material science, chemical engineering, architecture.   

Mechanics modeling and numerical simulations are fundamental tools in the investigation of a broad variety of physical phenomena and engineering problems, and in particular in biomechanics and biomimetic mechanics. By mechanical models, we can probe real situations simply and predict the behaviour of these complicated biological systems accurately.

In this special issue, we will collect recent advances on biomechanics and biomimetic mechanics. This topic may deal with: mechanics of tissues or organs on biology; biomimetics on surface or interface and wetting problems; cell mechanics; locomotion of animals; mechanical behaviors of plants; mechanical response of biology in multi-physical fields, etc. In this special issue, we mainly collect works with skills in modeling and numerical simulations, related to biomechanics and biomimetic mechanics. We expect these studies can enrich our knowledge on the bio-inspired world, and widen our eyes in exploring this world: beautiful and colorful.

    Crashworthiness Design and Multi-Objective Optimization for Bio-Inspired Hierarchical Thin-Walled Structures

    Shaoqiang Xu, Weiwei Li, Lin Li, Tao Li, Chicheng Ma
    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.2, pp. 929-947, 2022, DOI:10.32604/cmes.2022.018964

    Abstract Thin-walled structures have been used in many fields due to their superior mechanical properties. In this paper, two types of hierarchical multi-cell tubes, inspired by the self-similarity of Pinus sylvestris, are proposed to enhance structural energy absorption performance. The finite element models of the hierarchical structures are established to validate the crashworthiness performance under axial dynamic load. The theoretical model of the mean crushing force is also derived based on the simplified super folded element theory. The finite element results demonstrate that the energy absorption characteristics and deformation mode of the bionic hierarchical thin-walled tubes are further improved with the… More >

    Study of Effect of Boundary Conditions on Patient-Specific Aortic Hemodynamics

    Qingzhuo Chi, Huimin Chen, Shiqi Yang, Lizhong Mu, Changjin Ji, Ying He, Yong Luan
    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.1, pp. 31-47, 2022, DOI:10.32604/cmes.2022.018286

    Abstract Cardiovascular computational fluid dynamics (CFD) based on patient-specific modeling is increasingly used to predict changes in hemodynamic parameters before or after surgery/interventional treatment for aortic dissection (AD). This study investigated the effects of flow boundary conditions (BCs) on patient-specific aortic hemodynamics. We compared the changes in hemodynamic parameters in a type A dissection model and normal aortic model under different BCs: inflow from the auxiliary and truncated structures at aortic valve, pressure control and Windkessel model outflow conditions, and steady and unsteady inflow conditions. The auxiliary entrance remarkably enhanced the physiological authenticity of numerical simulations of flow in the ascending… More >

    Yichen Lu, Zongning Chen, Enyu Guo, Xiangqing Kong, Huijun Kang, Yanjin Xu, Rengeng Li, Guohua Fan, Tongmin Wang
    CMES-Computer Modeling in Engineering & Sciences, Vol.127, No.2, pp. 705-720, 2021, DOI:10.32604/cmes.2021.015426

    Abstract In this study, the real 3D model of the feather shaft that is composed of medulla and cortex is characterized by X-ray computer tomography, and the structural features are quantitatively analyzed. Compression and tensile tests are conducted to evaluate the mechanical performance of the feather shaft and cortex at different regions. The analysis of the 3D model shows that the medulla accounts for ∼70% of the shaft volume and exhibits a closed-cell foam-like structure, with a porosity of 59%. The cells in the medulla show dodecahedron and decahedron morphology and have an equivalent diameter of ∼30 μm. In axial compression,… More >
