“…Herein, the new type of automotive crash box is designed by variable-thickness rolled blank, the rolling processes of which are shown in Fig. 2 [27]. The variablethickness rolled blank consists of different thickness zones and transition zones, where the transition zones are used to link different thickness zones.…”

“…How to exhaust the potential of materials according to the performance requirements is one of the most important issues for automotive lightweight design. Fortunately, variable-thickness rolled blank can vary the blank thickness with a continuous thickness transition through adjusting the roll gap [27]. This innovative technology can easily realize the customized thickness of a new type of automotive crash box.…”

“…Note that different thickness distributions of the variable-thickness rolled blanks lead to different performance; therefore, it is necessary to optimize the thickness distributions to maximize performance [28]. The optimal thickness distribution among different zones including the thin zones, thickness zones, and transition zones should satisfy a variety of manufacturing constraints [27], which are typical linear/nonlinear and inequality/equality constraints.…”

In many real-world engineering applications, a uniform design needs to be conducted in a constrained experimental domain that includes linear/nonlinear and inequality/equality constraints. In general, these constraints make the constrained experimental domain small and irregular in the decision space. Therefore, it is difficult for current methods to produce a predefined number of samples and make the samples distribute uniformly in the constrained experimental domain. This paper presents a two-phase differential evolution for uniform designs in constrained experimental domains. In the first phase, considering the constraint violation as the fitness function, a clustering differential evolution is proposed to guide the population toward the constrained experimental domain from different directions promptly. As a result, a predefined number of samples can be obtained in the constrained experimental domain. In the second phase, maximizing the minimum Euclidean distance among samples is treated as another fitness function. By optimizing this fitness function, the samples produced in the first phase can be scattered uniformly in the constrained experimental domain. The performance of the proposed method has been tested and compared with another state-of-the-art method. Experimental results suggest that our method is significantly better than the compared method in the uniform designs of a new type of automotive crash box and five benchmark test problems. Moreover, the proposed method could be considered as a

“…Bamboo [15, 16], horsetails [17, 18], and cattail [19] are kinds of gradient composite material with good mechanical properties in the natural environment. Due to bamboo's low density, it has a higher stiffness-mass ratio than some metallic materials such as steel and aluminum.…”

Many materials in nature exhibit excellent mechanical properties. In this study, we evaluated the bionic bumper structure models by using nonlinear finite element (FE) simulations for their crashworthiness under full-size impact loading. The structure contained the structural characteristics of cattail and bamboo. The results indicated that the bionic design enhances the specific energy absorption (SEA) of the bumper. The numerical results showed that the bionic cross-beam and bionic box of the bionic bumper have a significant effect on the crashworthiness of the structure. The crush deformation of bionic cross-beam and box bumper model was reduced by 33.33%, and the total weight was reduced by 44.44%. As the energy absorption capacity under lateral impact, the bionic design can be used in the future bumper body.
