Abstract: Bolted flange joints are widely used to connect pressure vessels and piping equipment together and facilitate their disassembly. Initial tightening of their bolts is a delicate operation because it is extremely difficult ...

Abstract: Bolted flange joints are extensively used in pressure vessels and piping equipment and rotating machinery. Achieving a uniform bolt preload during the assembly process is particularly important to satisfy tightness in ...

Abstract: Understanding the elastoplastic contact loading–unloading behavior between a sphere and a rigid plane is a problem in the field of contact mechanics. In this study, a bilinear strain-hardening material model was used to ...

Abstract: In this study, an analytical approach based on the energy method is used to estimate the force required to expand tubes with different die shapes. The proposed method calculates the driving force using the energy of ...

Abstract: As a crucial component, rolling bearings directly determine the reliability of rotating equipment. However, current dynamic models for predicting the bearing performance either ignore the velocity and stress dispersion at ...

Abstract: Bolted flange joints are widely used in the nuclear power plants and other industrial complexes. During their assembly, it is extremely difficult to achieve the target bolt preload and tightening uniformity due to elastic ...
