This paper investigates the crashworthiness performance of square pipes with induced holes. Glass reinforced epoxy (GFRP) specimens were fabricated and tested under quasi-static axial crashing. Four design parameters were chosen, each at three levels, to calculate crashworthiness indicators. The design parameters are the hole diameter (d), the hole position to specimen length ratio (P/L), the number of holes and distribution (n), and crosshead speed (V). Taguchi technique has been adapted to get the optimum crashworthiness parameters. Experiments based on Taguchi’s orthogonal array with 9 experimental runs (L9) were performed. Optimal conditions with the maximum absorbed energy (U) and minimum initial peak force ([Formula: see text]) were determined. The main effects, signal to noise ratio (S/N), and analysis of variance (ANOVA) have been investigated. Results indicated that “V” followed by “d” are the highest influencing parameters on the values of “U” with a contribution of 49% and 43%, respectively. The dominant influencing parameter on the values of [Formula: see text] is “n” with a contribution of 94%. Finally, confirmation tests were carried out to validate the estimated model with respect to experimental results. The optimum U and [Formula: see text] of GFRP square pipes with circular cutouts were compared with those of non-porous specimens.

“…where γ i represents the estimated GRG for each ith experiment, the larger its value, the better. Various studies support the application of the Grey-Taguchi method in the (multiobjective) optimization of processes and products, in the area of materials and manufacturing [36][37][38]. However, its application in environmental engineering is limited, even more so in AOP optimization; being that most of the works use the traditional Taguchi method to optimize the photo-Fenton process in a single response variable.…”

“…This allows the conversion of the optimization of multiple and cated performance characteristics into a single variable (grey relational degree) This method emerged at the end of the 1980s and since then its application in vario has grown almost exponentially (Figure 2A). Although the Grey-Taguchi meth been successfully applied in other areas (especially those related to manufacturing 2B) [36][37][38][39], its application in AOP optimization is limited. To our best knowledge, there is no application of the Grey-Taguchi method to the optimization of the pho ton process.…”

Currently there is a growing concern about the presence of emerging contaminants (EC) in water bodies and their potential ecotoxicological effects. Pharmaceuticals, a type of EC, are widely distributed in the environment and their main entry is through wastewater from treatment plants, since these systems are not designed to remove EC. In this sense, the photo-Fenton process, an advanced oxidation process, has proven to be highly efficient in degrading new potentially harmful contaminants. However, this process is affected by multiple factors, which makes it necessary to implement a methodological strategy to optimize the photo-Fenton process. Within these, the Taguchi method provides robust and low-cost solutions with the least number of experiments, providing knowledge of the contribution of each of the factors studied to the response variable. In addition to the above, the Taguchi method can be coupled to a Grey relational analysis (Grey–Taguchi method), which will allow the optimization of more than one response variable at the same time. This paper discusses the parameters that affect the photo-Fenton process and the application of designs of experiments to optimize the process.

“…The introduction of bearings into the model is very necessary for accurate bird strike simulation. Furthermore, the mass and flight velocity of the bird also affect the bird strike results [26]. Although many bird strike scenarios have been studied previously, the parametric study of a real bird model striking a rotating fan with bearings has not been investigated before.…”

Bird strikes are one major accident for aircraft engines and can inflict heavy casualties and economic losses. In this study, a smoothed particle hydrodynamics (SPH) mallard model has been used to simulate bird impact to rotary aero-engine fan blades. The simulations were performed using the finite element method (FEM) at LS-DYNA. The reliability of the material model and numerical method was verified by comparing the numerical results with Wilberk’s experimental results. The effects of impact and bearing parameters, including bird impact location, bird impact orientation, initial bird velocity, fan rotational speeds, stiffness of the bearing, and the damping of the bearing on the bird impact to aero-engine fan blade are studied and discussed. The results show that both the impact location and bird orientation have significant effects on the bird strike results. Bird impact to blade roots is the most dangerous scenario causing the impact force to reach 390 kN. The most dangerous orientation is the case where the bird’s head is tilted 45° horizontally, which leads to huge fan kinetic energy loss as high as 64.73 kJ. The bird’s initial velocity affects blade deformations. The von Mises stress during the bird strike process can reach 1238 MPa for an initial bird velocity of 225 m/s. The fan’s rotational speed and the bearing stiffness affect the rotor stability significantly. The value of bearing damping has little effect on the bird strike process. This paper gives an idea of how to evaluate the strength of fan blades in the design period.
