Getting started with analyzing thin-walled pressure vessels in a SOLIDWORKS simulation

This first case study demonstrates one of the modeling/simulation approaches for simulating thin-walled pressure vessels. As part of this demonstration, this section illustrates creating a thin surface from a thin-walled body. It also highlights how to apply pressure loads and symmetric boundary conditions. In addition, mesh refinements and methods will be provided so that you can compare the results of multiple simulation studies.

Let's get started.

Problem statement – case study 1

A thin cylindrical vessel with hemispherical heads, as depicted in the following diagram, is to be used as a gas storage tank. It is expected to withstand an internal pressure of 7 MPa. The tank is made of steel with Young's modulus of 200 GPa and a Poisson's ratio of 0.3. The internal diameter, length, and thickness of the cylinder are 75 mm, 250 mm, and 2.5 mm, respectively.
