In international finance, intermarket connectedness and dependence are crucial factors that provide valuable insights for fund managers and policymakers. However, with the increasing reliance on fossil-fuel based economies, the emission of climate risks has become a significant concern in recent years. To promote sustainability, the adoption of clean energy has emerged as a promising approach to combat the climate risks associated with conventional energy systems (Chen et al., 2022a).

Abstract During the thermal simulation compression test, the formation of an obvious bulge in the specimen leads to a certain deviation between the calculated and actual values of the true stress. The finite element method was used to simulate the single-pass compression of specimens of 34CrNi3MoV steel and obtain the actual nonuniform deformation of the bulging belly during the compression process, and the results were applied to correct experimental flow curves.

Abstract : Bearings are usually used at high-speed and high-load conditions, so the bearing sleeve must be able to withstand large contact stress, which requires heat treatment. However, during the quenching process of the bearing sleeve, a vapor film is formed on the surface. Since the vapor film is not uniform along the axial direction during the process of boiling and breaking, it will cause uneven distortion of the bearing sleeve.
