Abstract

Helicoidal schemes possessed by biological creatures possess high strength and stiffness. The adoption of the layup configurations possessed by these biological creatures is not fully explored. The present article aims to carry out the free vibration analysis of biological-inspired laminated composite (B-ILC) plates having helicoidal layup. The analysis is carried out using higher-order zigzag theory (HOZT) as due to the presence of several layers, the HOZT can predict the behavior accurately compared to the shear deformation theory. Based on Hamilton’s principle, the governing equations are worked out and analyzed using the finite element method. The influence of boundary conditions, geometric properties, number of layers, the skew angle of the plate, and material properties on the free vibration behavior are studied in detail.

仿生螺旋面层合复合材料板的自由振动分析

生物所具有的螺旋结构具有较高的强度和刚度。这些生物所拥有的叠置结构的采用并没有得到充分的探讨。本文的目的是对具有螺旋层合的生物启发层合复合材料(B-ILC)板进行自由振动分析。采用高阶之字形理论(HOZT)进行分析，因为与剪切变形理论相比，由于多层结构的存在，高阶之字形理论可以准确地预测其行为。根据哈密顿原理，建立了控制方程，并用有限元法对其进行了分析。详细研究了边界条件、几何特性、层数、板的倾斜角和材料特性对自由振动性能的影响。

期刊介绍： The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice. "Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications."
