Nowadays, the minimization of energy, costs, and resource consumption of industrial products through their lifecycle is at the center of the industry and research community attention. Ideally, all these factors should be considered during the design phase of the component. Although there are many efforts to formulate indicators that can establish the ecological and economic performance of an artifact, less frequent are the attempts to formalize methods that allow for the identification of design variables as the output of an optimization process that previously includes environmental, energy, and cost requirements. This work is an attempt to formulate a methodology that allows the determination of design variables to be obtained downstream of the analysis, which, bound to the fulfilment of predefined structural requirements, are such as to optimize certain objectives of minimizing monetary and environmental costs. The proposed approach has been specified for a case of study dealing with metal section beams, on which a database has been collected about the environmental and economic characteristics of the sources of supply, the usable materials, and the technological processes. This method allows an accurate modeling of the possible production cycles and, on the basis of this, to formulate functional links between the mechanical properties of the structure and the most representative quantities related to environmental impact and costs.

“…Li [ 21 ] employed ANSYS to analyze the fatigue performance of composite bamboo columns reinforced with GFRP and showed that GFRPs can effectively improve the fatigue life of the bamboo columns. Donato et al [ 22 ] designed a bamboo treadmill bike through ABAQUS and analyzed its characteristics of stiffness and structural strength, and the results revealed that the main frame made of bamboo could meet specification requirements and actual needs.…”

As an ecological green building material, natural bamboo has many advantages such as a light weight, high strength, and short growth cycle. Natural bamboo is widely used in landscape architecture and fabricated structures. However, in bamboo building structures, the most common bolted joints often appear cleaved along the grain. In this paper, glass fiber-reinforced polymer (GFRP) is designed to wrap and improve the shear capacity of natural bamboo-bolt composite joints. According to the corresponding material parameters, the finite element model of composite joints is established, and the key influencing variables of the bearing capacity, namely the bolt diameter, bamboo tube outer diameter, and screw end distance, are analyzed. In addition, according to the European analytical yield model of bolted connections, the analytical calculation method of the bearing capacity is proposed and compared with the experimental and simulated values. The results showed that the numerical model and the modified analytical model can suitably describe the bearing capacity of composite joints, and a higher bolt diameter, along with the bamboo outer diameter, will lead to a higher ultimate load of the composite joints. Moreover, the bearing capacity of composite joints has no obvious relationship with the end spacing.

[10][11][12][13][14][15][16][17][18] In particular, this paper deals with the development of two FE models aimed to assess the safety of a physical hydrogen tank against two crash events. The design of the hydrogen tank shall take into account the service and test pressures, the external stresses caused by the operating loads (like impacts, aggressive media, vibrations, service temperature, weight of connectors), the real lifetime (cycling), and the safety coefficients defined for both static and dynamic conditions.…”

In near future, the main challenge is to reduce the use of fossil fuels that currently emit the bulk of global CO2 emissions, responsible of the global warming and climate change. Hydrogen, as a future fuel candidate, would play a significant role for net‐zero emission requirements. As a matter of fact, new hydrogen tank design is needed to bring this technology to the readiness level. This paper aims to investigate on the impact resistance of a hybrid aluminum‐composite hydrogen tank. In particular, the paper presents the development of two finite element (FE) models for the simulation of two impact scenarios experimentally investigated and proposed in literature. The models provided acceptable levels of accuracy with consequent benefits in supporting designers in the certification process of such device type.
