DESIGN AND STRESS ANALYSIS OF PRESSURE VESSEL BY USING ANSYS

The pressure vessel is o ne of a large number of plant components for which stress analyses must be performed. A pressure vessel experiences mainly two types of stresses, primary stresses and secondary stresses. Primary stresses are because of pressure inside pressure vessel and s econdary stresses are because of thermal loading. Thermal loading is considerable in a pressure vessel which handles hot fluid. Typically liquid metal reactors (LMR) have thermo - mechanical loadings. Analytically, induced stresses are calculated using press ure vessel theory or ASME codes. In this project induced stresses are calculated using ANSYS coupled field analysis for thermo - mechanical loading. The results are then compared with analytical results. This work demonstrates usage of commercial FEA tool ov er analytical approach. Analytical solutions such as ASME and Japanese Code give empirical relationships to calculate thermal stress. Use of FEA tools is not very popular in pressure vessel industries. FEA of this kind of loading requires coupled field ana lysis. In the work ANSYS is used to perform coupled field analysis.
