Instrumented Pressure Vessel Stress Analysis Using Finite Element Analysis (FEA)

The Instrumented Pressure Vessel (IPV) shown below was subjected to an external pressure of 1500 psi (10.2 mPa). This is equivalent to a seawater depth of 3375 ft (1029 m).

A Finite Element Analysis (FEA) was performed on this IPV using SOLIDWORKS SIMULALTION.

PRESSURE VESSEL FEA, EXTERNAL PRESSURE = 1500 PSI (10.3 mPa)

IPV Subjected to an External Pressure of 1500 PSI (10.3 mPa)

The image above shows the FEA results of the IPV when subjected to a pressure of 1500 psi (10.3 mPa). The  maximum stress is shown to be about 12.7 ksi (87.3 mPa). This is about 32% of the IPV's material yield strength.

Finite Element Analysis (FEA)

FEA is used to calculate stress and deflection in machine parts, assemblies, weldments, and sheet metal parts.

These parts have geometries that don't allow the use of Classical Stress Analysis methods.

SolidWorks Simulation

SolidWorks Simulation improves product reliability by optimizing parts and assemblies for many environments and scenarios. It is a cost effective way to predict a product's real world physical behavior by virtually testing Computer Aided Design (CAD) models.
