Research and application of bending forming limit of high-strength wear-resistant steel

    
    High strength wear-resistant steel has been widely used in various industries due to its superior performance. However, the application of this type of steel is strictly limited by its bending forming limit. In recent years, various related research experiments have been conducted based on the methodology of finite element calculation and the experimental optimization strategy of tribology. The purpose of these research projects is to study the bending forming limit of high strength wear-resistant steel and optimize the bending forming process.
    
    First of all, in order to accurately predict and analyze the bending forming limit of high strength wear-resistant steel, finite element calculation can be used. This calculation method mainly consists of three parts: the evaluation of stress and strain, the determination of stress-strain relationships, and the investigation of fatigue failure. Through a finite element method, the elastic and plastic characteristics of the material can be determined, and the effects of small deformation conditions can be analyzed. Experiments which were designed and optimized based on the finite element calculation can then be conducted to further characterize and test the material performance.
    
    Extra research and experiments may be necessary in order to accurately predict the forming limit of high strength wear-resistant steel. A typical research experiment goes as follows. Firstly, an experiment is designed through various pre-processing steps such as generating a finite element model, mesh generation, user defined material properties, contact conditions and mesh distribution, etc. Within the experiment, the stresses and deformations in the steel can be measured under cyclic loading and corresponding fatigue fracture surfaces can be examined.
    
    Secondly, the analysis and prediction of the forming limit should be done after the completion of the experiment. Generally, the analysis and prediction of the bending forming limit can be conducted considering the influence of the microstructure, composition and forming process parameters on the forming limit of the high strength wear-resistant steel.

    Finally, the optimization of the forming process should be investigated to enhance the bending forming limit of the high strength wear-resistant steel. This could include the optimization of the forming temperature, the optimization of the pre-stress, the optimization of the surface roughness and material anisotropy, the optimization of the tool material, and other optimization strategies based on tribology.
    
    Through the combination of finite element calculation and tribological optimization strategy, the bending forming limit of high strength wear-resistant steel can be accurately calculated, predicted and optimized. This can provide theoretical guidance and optimization strategies for the bending process of high strength wear-resistant steel and contribute to the development of better tribological and forming performance.
    
    In conclusion, the bending forming limit of high strength wear-resistant steel can be accurately analyzed and predicted with simulations and experiments. In addition, tribological optimization strategies can further enhance the bending forming limit of the steel and provide better application methods for the industrial development.
