Abstract

Bird strikes can potentially damage the aerospace and aeronautics structures and cause serious damage to the structure. In the present work, damage due to bird-strike in bio-inspired helicoidal laminated composite plates with circular and elliptical holes is predicted using Smoothed Particle Hydrodynamics (SPH)-Finite Element Method (FEM) model in ABAQUS. The Hashin failure model within ABAQUS has been implemented to model the impact-induced damage. The bird is modelled using the concepts of SPH to handle the mesh deformation problem effectively. Helicoidal recursive, exponential, semi-circular, linear, and Fibonacci helicoidal are studied during the present study. The plate is considered with two holes located at a quarter distance along the middle vertical axis of the plate. The damage in exponential, recursive, and linear helicoidal laminates is lesser than in conventional cross-ply and quasi-isotropic laminates. The plate with small dimensions of circular holes tends to deflect the failure in fibres towards the corners, while the plate with many holes arrests the cracks themselves. The plate with elliptical holes deflects the cracks towards themselves thus preventing the damage near the edges but damages the laminate in its vicinity.

带孔仿生层合板的鸟击损伤研究

鸟击有可能破坏航空航天结构，对结构造成严重损害。本研究利用 ABAQUS 中的平滑粒子流体力学（SPH）-有限元法（FEM）模型，预测了带圆孔和椭圆孔的生物启发螺旋形层压复合板因鸟击造成的损坏。ABAQUS 中的 Hashin 失效模型用于模拟冲击引起的损坏。该模型使用 SPH 概念有效处理网格变形问题。本研究对螺旋递归、指数、半圆、线性和斐波那契螺旋进行了研究。考虑到板上有两个孔，位于板中间垂直轴的四分之一处。与传统的交叉层压板和准各向同性层压板相比，指数、递归和线性螺旋形层压板的损伤较小。圆孔尺寸较小的层压板往往会将纤维的破坏偏向边角，而孔洞较多的层压板则会阻止裂缝的产生。带有椭圆孔的板可使裂缝向自身偏转，从而防止边缘附近的损坏，但会损坏其附近的层压板。
