“…But the bending deformation was not enough to induce the cells of the aluminium honeycomb debonding from the adjacent adhesive layers. erefore, the damage of degumming between aluminium honeycomb cell layers was not found in these three-point bending tests [23].…”

e aim of this paper was to investigate bending responses of sandwich panels with aluminium honeycomb core and carbon fibrereinforced plastic (CFRP) skins used in electric vehicle body subjected to quasistatic bending. e typical load-displacement curves, failure modes, and energy absorption are studied. e effects of fibre direction, stacking sequence, layer thickness, and loading velocity on the crashworthiness characteristics are discussed. e finite element analysis (FEA) results are compared with experimental measurements. It is observed that there are good agreements between the FEA and experimental results. Numerical simulations and experiment predict that the honeycomb sandwich panels with ±30°and ±45°fibre direction, asymmetrical stacking sequence (45°/−45°/45°/−45°), thicker panels (0.2 mm∼0.4 mm), and smaller loading velocity (5 mm/min∼30 mm/min) have better crashworthiness performance. e FEA prediction is also helpful in understanding the initiation and propagation of cracks within the honeycomb sandwich panels.

“…e curves can be divided into two stages, namely, the initial elastic bending stage and bending collapse stage [23]. Taking the specimens of Case D (D1, D2, and D3) as an example, in the initial elastic bending stage, the bending load kept increasing until it reaches the first peak (the average value is 435 KN).…”

“…The basic strategy to model the individual damage mechanisms was to define the damage model for different components, respectively. To simulate the low velocity impact response of composite sandwich structure, the continuum damage mechanics based damage criteria were defined for predicting the intra-laminar damage of composite face sheet with delamination using cohesive zone elements while the mechanical behaviour of honeycomb core can be modelled, referring to the experimentally measured data (Aktay et al 2008;Liu et al 2017) or damage model for Nomex (Chen et al 2017;Liu et al 2015;Giglio et al 2012) or Aluminium honeycomb (Lee et al 2010;Kay 2003).…”

The paper presents recent progress on modelling low velocity impact induced damage in fibre reinforced composite laminates. It is important to understand the mechanisms of barely visible impact damage (BVID) and how it affects structural performance. To reduce labour intensive testing, the development of finite element (FE) techniques for simulating impact damage becomes essential and recent effort by the composites research community is reviewed in this work. The FE predicted damage initiation and propagation can be validated by Non Destructive Techniques (NDT) that gives confidence to the developed numerical damage models. A reliable damage simulation can assist the design process to optimise laminate configurations, reduce weight and improve performance of components and structures used in aircraft construction.

“…Composite materials, such as carbon fibre or glass fibre reinforced polymer, are increasingly desired in a number of applications such as aerospace, automotive, marine, infrastructural, renewable energy, biomedical and consumer products, due to their high ultimate strength, elastic moduli, high strength-to-weight-ratio and better failure reliability [1,2,3]. Furthermore, there are state-of-the-art development of multi-functional smart composite materials [4] that attempts to achieve the additional functionalities such as energy harvesting, structural health monitoring (SHM), condition sensing and wireless communication onto the otherwise purely mechanical material by integrating the multifunctional elements together.…”

This paper presents a finite element (FE) model developed using commercial FE software COMSOL to simulate the multiphysical process of pieozoelectric vibration energy harvesting (PVEH), involving the dynamic mechanical and electrical behaviours of piezoelectric macro fibre composite (MFC) on carbon fibre composite structures. The integration of MFC enables energy harvesting, sensing and actuation capabilities, with applications found in aerospace, automotive and renewable energy. There is an existing gap in the literature on modelling the dynamic response of PVEH in relation to real-world vibration data. Most simulations were either semi-analytical MATLAB models that are geometry unspecific, or basic FE simulations limited to sinusoidal analysis. However, the use of representative environment vibration data is crucial to predict practical behaviour for industrial development. Piezoelectric device physics involving solid mechanics and electrostatics were combined with electrical circuit defined in this FE model. The structure was dynamically excited by interpolated vibration data files, while orthotropic material properties for MFC and carbon fibre composite were individually defined for accuracy. The simulation results were validated by experiments with <10% deviation, providing confidence for the proposed multiphysical FE model to design and optimise PVEH smart composite structures.
