“…The mechanical characterization process of a material is critical in determining its reliability and mechanical performance, particularly under real-world applications under impact conditions, e.g., vehicle collision [ 3 , 4 ], bird strike [ 5 , 6 ], and sports impact [ 7 ]. Traditional standardized test procedures are typically performed under quasi-static conditions [ 8 , 9 , 10 , 11 , 12 , 13 ].…”

A dynamic tensile experiment was performed on a rectangular specimen of a non-crimp fabric (NCF) thermoplastic composite T700 carbon/polyamide 6.6 specimens using a split Hopkinson pressure (Kolsky) bar (SHPB). The experiment successfully provided useful information on the strain-rate sensitivity of the NCF carbon/thermoplastic material system. The average tensile strength at three varying strain rates: 700, 1400, and 2100/s was calculated and compared to the tensile strength measured from a standardized (quasi-static) procedure. The increase in tensile strength was found to be 3.5, 24.2, and 45.1% at 700, 1400, and 2100/s strain rate, respectively. The experimental findings were used as input parameters for the numerical model developed using a commercial finite element (FE) explicit solver LS-DYNA®. The dynamic FE model was validated against experimental gathering and used to predict the composite system’s behavior in various engineering applications under high strain-rate loading conditions. The SHPB tension test detailed in this study provided the enhanced understanding of the T700/polyamide 6.6 composite material’s behavior under different strain rates and allowed for the prediction of the material’s behavior under real-world, dynamic loading conditions, such as low-velocity and high-velocity impact.

“…For bird-strike related problems, almost 49% of researchers preferred the Lagrange model where 37% of researchers employed SPH to predict results (Heimbs, 2011). However, most of the recent works investigated the bird impact issues are carried out using the SPH method (Such as: Eren et al, 2017;Kim and Kim, 2017;Zhou et al, 2019b;Zhou et al, 2019c;Jang and Ahn, 2018;Zhang et al, 2018;Qiu et al, 2020;Yu et al, 2019). The main reason of adopting SPH is that it can predict fairly accurate results in comparison to experiments and the recent advancement of parallel computing has brought down the solution time significantly, which was previously the main obstacle of using this method.…”

Numerical simulation plays a crucial role in today's aviation industry. Modern computers with the latest commercial FE codes have fueled the triumph of establishing simulation as a prerequisite of aerostructure part design from micro modeling of materials to large-scale structural analysis. In this current research paper, a Mooney-Rivlin material model of ballistic gelatin with Lagrange code is analyzed as a potential candidate for the computational bird model to simulate bird strike case studies. To investigate the practicability, the model is compared with other established Lagrange and SPH EOS models for both rigid and deformable body impacts along with experimental data found in the literature adopting explicit solver Ansys Autodyn. Despite some discrepancies found during rigid body impacts, deformable plate impacts confirm the robustness of the model with significantly faster computation time. Besides, the biggest criticism of the Lagrange model, mesh distortion problem as fluid during bird strike case studies is efficiently tackled by adopting the node erosion algorithm as an effective technique to solve Lagrange bird models without affecting the outcome of the solutions.

“…Coherence function drops, harmonic distortion, and singularities in the Holder exponent were also applied to identify the damage signature in the system response [6]. Moreover, nonlinear acoustic and vibration-based methods have been widely used for damage detection [7][8][9][10][11][12]. To identify damage in composite materials some techniques focused on specific features of the elastic system response such as wave modulation and cross-modulation [13][14][15][16], sidebands [7,17], higher and sub-harmonic generation, hysteretic behavior and nonlinear slow dynamics [18].…”

To detect the presence of damage, many structural health monitoring techniques exploit the nonlinear features that typically affect the otherwise linear dynamic response of structural components with internal defects. One of them is the Scaling Subtraction Method (SSM), which evaluates nonlinear features of the response to a high-amplitude harmonic excitation by subtracting a scaled reference signal. Originally tested on granular materials, the SSM was shown to be effective for composite materials as well. However, the dependence of the technique efficiency on the testing frequency, usually selected among the natural frequencies of the system, may limit its application in practice. This paper investigates the feasibility of applying the SSM through a broadband impulsive excitation, which would avoid the need of a preliminary modal analysis and address the issue of the proper selection of the excitation frequency. A laminated composite beam was tested in intact and damaged conditions under both scaled harmonic excitations of different frequency and broadband impulsive signals of scaled amplitude. Two damage indicators working on the frequency domain were introduced. The results showed a good sensitivity of the SSM to the presence and level of impact damage in composite beams when applied through a broadband impulsive excitation.
