COMPARATIVE ASSESSMENT OF PIPING STRESS ANALYSIS SOFTWARE: CAESAR-II, AUTOPIPE, AND ANSYS APPROACHES

Abstract

Piping stress analysis software is a type of assessment needed to provide the structural reliability and safety of complex
piping system under high pressure, temperature, and dynamic loading conditions. The given paper presents an extensive review of
comparative analysis of three most popular tools CAESAR-II, AutoPIPE and ANSYS which are commonly used in the field of
industrial design and analysis. Both software use different computational techniques and modeling tools to estimate stress,
deformation and failure propensity in piping systems. The CAESAR-II and AutoPIPE mainly adhere to code-based analysis
techniques of flexibility with more lean, global-level stress analysis in concurrence with international design standards like ASME
B31.1 and B31.3. ANSYS on the other hand employs Finite Element Method (FEM) to determine the stress distribution detail and
nonlinear response analysis in three-dimensional analysis and offers enhanced accuracy in localized analysis. This paper discuss
their advantages in analysis, modeling, weaknesses, and their use in industries. In addition, the review incorporates new findings
in the fields of fluid-structure interaction, thermal analysis, and fatigue analysis of piping systems. The purpose of this comparative
analysis is to examine how computational predictions and real-world outcomes differ and how to improve them. It is suggested
that artificial intelligence, hybrid FEM code coupling and auto simulation workflow integration is introduced in the future to
advance efficiency, accuracy and predictive maintenance in the design of modern piping systems.
