DESIGN AND STRESS ANALYSIS OF PRESSURE VESSEL BASED ON ANSYS

Abstract

The pressure vessel is a critical component in many industrial plants, requiring thorough stress analysis to ensure safety and reliability. These vessels are subjected to both primary stresses from internal pressure and secondary stresses due to thermal loading, the latter being significant in vessels containing hot fluids. For instance, liquid metal reactors (LMRs) experience complex thermo-mechanical loadings. Traditional analytical methods, such as those prescribed by ASME codes, are typically used to calculate these induced stresses. However, in this project, A coupled field study is carried out using ANSYS software to get a more thorough knowledge of thermo-mechanical stressesWhen the outcomes from ANSYS and conventional analytical techniques are compared, it becomes clear how useful commercial finite element analysis (FEA) tools are for designing pressure vessels. Although FEA is not widely adopted in the industry for such analyses, this project demonstrates its potential advantages, particularly in handling coupled field analysis involving thermal and mechanical loads.
