“…Transient research was used in this study. For the solution of the transient models, their accuracy was limited by the resolution of the grid in space for waves and the resolution of the time step for temporal changes [31]. Depending on the actual needs of the model, there were different standards for dividing the grid size.…”

Accurate measurement of the stress in steel structures is crucial for structural health monitoring. To achieve this goal, a novel technique, the laser ultrasonic technique, was used in absolute stress measurement in this study. The feasibility of this technique has been verified through theoretical analysis and finite element (FE) analysis. A stress measurement experiment in steel specimens was conducted and the relationship between ultrasonic relative wave velocity and stress was explored. The results revealed that there is a similar linear correlation between the ultrasonic relative wave velocity and absolute stress. The stress can be obtained based on ultrasonic relative wave velocity. According to the stress measurement results, it was found that the absolute error between the measured stress and theoretical stress was largest when the stress level was low, and that the measured error of stress gradually decreased with increases in the applied stress. The relative error between the measured stress and the theoretical stress was within 10% when the stress was higher than 100 MPa. This further verifies the reliability of the laser ultrasonic technique under high-stress conditions. Additionally, the impact of temperature and surface roughness on stress measurement was analyzed. The stress error in stress measurement increased similarly linearly with the increase in temperature and increased non-linearly with the increase in roughness. The corresponding compensation methods were proposed to effectively improve the accuracy of measurement.

“…At present, many scholars have adopted theoretical analysis [ 7 , 17 ], numerical simulation [ 18 , 19 , 20 , 21 ] and experimental research methods [ 22 , 23 ]; there is systematic research on deformation instability in terms of materials, structure, boundary conditions and applications. That is, the research on the deformation instability of metal materials first needs to determine the instability behavior, establish the mathematical model, and obtain the analytical solution of deformation instability.…”

Deformation instability is a macroscopic and microscopic phenomenon of non-uniformity and unstable deformation of materials under stress loading conditions, and it is affected by the intrinsic characteristics of materials, the structural geometry of materials, stress state and environmental conditions. Whether deformation instability is positive and constructive or negative and destructive, it objectively affects daily life at all times and the deformation instability based on metal-bearing analysis in engineering design has always been the focus of attention. Currently, the literature on deformation instability in review papers mainly focuses on the theoretical analysis of deformation instability (instability criteria). However, there are a limited number of papers that comprehensively classify and review the subject from the perspectives of material characteristic response, geometric structure response, analysis method and engineering application. Therefore, this paper aims to provide a comprehensive review of the existing literature on metal deformation instability, covering its fundamental principles, analytical methods, and engineering practices. The phenomenon and definition of deformation instability, the principle and viewpoint of deformation instability, the theoretical analysis, experimental research and simulation calculation of deformation instability, and the engineering application and prospect of deformation instability are described. This will provide a reference for metal bearing analysis and deformation instability design according to material deformation instability, structural deformation instability and localization conditions of deformation instability, etc. From the perspective of practical engineering applications, regarding the key problems in researching deformation instability, using reverse thinking to deduce and analyze the characteristics of deformation instability is the main trend of future research.

To solve the problems of low strength and unsatisfactory connection quality of clinching in three-layer sheets, a method of clinching aluminum alloy three-layer sheets with an inclined wall die was proposed. AA5052 aluminum alloy sheets were chosen as the research objects. Elastic-plastic finite element simulation and experimental research were conducted to analyze the mechanism of clinching joints in three-layer sheets and a finite element method has been used to investigate and summarize the five stages of forming a three-layer aluminum sheet clinching. Six load distribution methods were designed to investigate the strength of clinching joints in three-layer sheets. The failure mode and failure mechanism of the joints in the shear and peel experiment were comprehensively studied. The comparison between the experimental and finite element results had an error of less than 8%, indicating that the finite element model was highly reliable. The failure strength of the joints and the energy absorption values were determined by physical experiments, and the results show that the D-2 joint has a maximum shear strength of 3400 N and an energy absorption of 6.67 J. The D-3 joint has a shear strength of 3040 N and an energy absorption of 9.29 J. The T joint has a lower strength and a higher failure displacement, with the T-3 joint having a maximum peel strength of 690 N and an energy absorption of 11.876 J.
