### 3.9.3 ASME Code Class 1, 2, and 3 Components,

3.9.3.1 Loading Combinations, System Operating Transients, and Stress Limits Section 3.9.3.1.1 describes the design and service level loadings used for the design of ASME Class 1, 2, and 3 components, piping, supports, and core support structures, including the appropriate system operating transients. Sections 3.9.3.1.2 through 7.2 Analysis of Three Dimensional Stress and Strain7.2 Analysis of Three Dimensional Stress and Strain . The concept of traction and stress was introduced and discussed in Book I, §3. For the most part, the discussion was confined to two-dimensional states of stress. Here, the fully three dimensional stress state is examined. There will be some repetition of the earlier analyses.

### ASME B31.3 Design for Sustained and Occasional Loads

Mar 11, 2018 · Although ASME B31.1 requires that 0.75 times the stress intensification factors be used, ASME B31.3 is silent on the issue. In the absence of explicit guidance, some writers of piping stress analysis programs have elected to use the full value of the stress intensification factors in the analysis of sustained loads for ASME B31.3 piping. ASME B31.3 Piping stress analysis bullet points (Part-1)Aug 21, 2018 · 3) Stress categories :-Stresses developed in piping system due to various types of loading are mainly categorized in Sustained Stress, Expansion Stress and Occasional Stress. (a) Sustained Stresses :Sustained Stresses are "Primary Stresses" developed in piping system due to "weight of piping component and pressure contained in pipe".

Analysis of strain. While defining a stress it was pointed out that stress is an abstract quantity which cannot be seen and is generally measured indirectly. Strain differs in this respect from stress. It is a complete quantity that can be seen and generally measured directly as a relative change of length or shape. In generally, stress is

### Basic stress analysis calculations - EngineeringClicks

Sep 12, 2017 · Similarly, for the calculation of the bending modulus, we use the formula Eb = FL 3 /4wt 3 y with y being the deflection at the load point. Finally, no basic stress analysis calculations guide would be complete without explaining how to calculate the max stress based on a selected safety factor. Chapter 11 Three-Dimensional Stress AnalysisThree-Dimensional Stress Analysis. Introduction In this chapter, we consider the three-dimensional, or solid, element. This element is useful for the stress analysis of general three- dimensional bodies that require more precise analysis than is possible though two-dimensional and/or axisymmetric analysis.

### How to perform a pipe stress analysis - Specifying Engineer

Sep 21, 2017 · Pipe stress analysis computer models are a series of 3-D beam elements that create a depiction of the piping geometry. Three-dimensional beam elements are the most efficient way to model the piping system, but not necessarily the most accurate; and without complex finite element models, it is nearly impossible to account for everything. Load Cases for Stress Analysis of a Critical Piping System The main objectives of stress analysis are to ensure:Structural Integrity (Design adequacy for the pressure of the carrying fluid, Failure against various loading in the life cycle and Limiting stresses below code allowable.)

### STRESS INTENSITY FACTOR (SIF) FOR SPECIAL GEOMETRIES

Stress Intensification Factor (SIF) is a multiplier factor on nominal stress obtained in a beam analysis (as for instance, calculations performed with CAESAR II software). ASME B31.1 and ASME B31.3 codes established the stress intensification factor (SIF) for geometries show in Stress Analysis of Process Pipe Line Systems (ASME B Piping stress analysis is a vital part of the Industrial plants condition assessment. At present, there are many softwares for piping stress analysis, viz.-CAEPIPE, CAESAR-II, AUTOPLANT, PIPE PACK, check STRESS, PDMS, etc. In this paper, piping stress analysis is carried out using CAESER-II
