DeepSea Power & Light: Under Pressure Design Software

"Under Pressure" Design Software

NEW WINDOWS VERSION
DESIGN LOOP ALLOWS VARIATION OF SINGLE PARAMETER
CALCULATES BOTH THIN WALL AND THICK WALL COLLAPSE PRESSURES
EQUATIONS FROM ROARK & YOUNG'S FORMULAS FOR STRESS AND STRAIN.

Summary

Under Pressure is an engineering design tool to aid in the design of pressure housings and pressure vessels. This program is used extensively for DeepSea's R&D and contract engineering. Designed to be used by the working engineer or scientist, this menu-driven software is interactive and user friendly. A large materials database is provided that can be expanded by the user.

The user can choose from a housing shape of tube, sphere, or endcap. Within the endcap category are several subcategories, such as hemispherical and flat annular. The flat annular endcap can be further delineated by choosing among several options, such as fixed, simply supported, guided, and free. The user also selects the material, housing component geometry, and pressure analysis range; the stress analysis is then rapidly calculated. A design loop can be selected and the analysis can be repeated while a single parameter (e.g. wall thickness) is varied. Stresses and deflections are given for internal or external pressures, over a user-selectable pressure range. English or metric units can be specified. The program uses equations from Formulas for Stress and Strain, sixth edition, by Raymond J. Roark and Warren C. Young.

Other features include:

Graphic representation of the pressure vessel,
On-line graphic display of radial and tangential stress distribution,
The manual contains a color comparison of numerical stress results with graphically displayed stress distribution results generated by a computer-aided structural analysis using the finite element method,
Complete hard-copy manual with step-by-step walk-through of Under Pressure’s features,

Soft copies of the manual are included in the CD in the original Microsoft Word format and in an Adobe Acrobat PDF format so that you can re-print the manual as needed.
