In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected for this experimental analysis, often used in many engineering applications. This alloy is not prone to corrosion as other austenitic steels with a higher share of carbon. Results show that material behaviour, in terms of dependence of stress intensity factor (SIF) value relative to thickness of the plate, is necessary to assume with a different model when the specimen thickness is very small. Application of standards in the field of investigation of material resistance to fracture allow simultaneous determination and connection of several fracture mechanics parameters.
Wind tunnel tests have been widely applied in aerodynamic investigations owing to their unique advantages. However, it is difficult to theoretically establish a simplified symmetry or two-dimensional model because of the relative motion of the structures and proximity of the train to the ground/infrastructure. Additionally, railway-related aerodynamic problems tend to be more challenging than those encountered in other engineering structures. Moreover, transient and crosswind effects, as well as complex operation environments, need to be considered, thereby making aerodynamic analyses of train–bridge systems challenging. Advanced manufacturing methodologies can reproduce realistic scenarios of high-speed train (HST) operations in a wind tunnel. The development of a controllable and affordable experimental method presents considerable research opportunities and challenges. There exists a strong correlation between wind tunnel experimental methods and the understanding of aerodynamic mechanisms, and some wind tunnel tests are dedicated to identifying the aerodynamic behavior using specific test systems. This study mainly describes the types of tests typically performed in a wind tunnel to analyze the aerodynamic issues of train–bridge systems under wind action. To identify and understand the individual role of the above mentioned-correlated systems, trains and bridges in wind tunnel tests are described separately. High-speed trains on bridges must be made safe and environmentally friendly, and a few cases are presented as indications to reconsider our aerodynamic research priorities. Thus, advanced experimental activities have been proposed in the Central South University (CSU) wind tunnel, representing helpful practices in defining the real-world aerodynamic behavior of wind-vehicle-bridge systems.
To solve the frequent urban flood problems, Sponge city, a novel city strategy-Sponge City, is a kind of water resource management strategy and method, which can adapt to the changes of rainwater like a sponge, so as to reduce the occurrence of flood problems. This paper reviewed the initiative and development of sponge city. It analyzed the problems faced by sponge city construction and possible solutions. In addition, pavement material was an important part of sponge city construction. This paper also reviewed the application and development of pavement materials in sponge city. Firstly, the commonly used permeable pavement materials were introduced including permeable asphalt concrete, permeable cement concrete, permeable brick, and novel pavement materials. To meet the requirements of “infiltration, retention, purification, evaporation, and drainage”, the pavement materials were designed to be porous. The pore characteristics were studied, including but not limited to porosity and pore size, etc. In addition, environmental assessment and economic analysis were conducted. It was found that the permeable pavements were not necessarily more environmentally friendly than traditional pavement, but they did have some obvious benefits such as water purification, traffic noise reduction, Urban Heat Island (UHI) mitigation, and waste materials recycling. There was a controversy about whether permeable pavements were more economical than traditional pavements. Finally, this paper looked forward to the future development of pavement materials in sponge city, which called for better hydrological performance and wider application range.
