Process Piping

Fitness-for-Service (FFS) is an assessment that is carried out using standardized methods and criteria, that evaluates the structural integrity of an asset/component to determine whether the asset/component is suitable for its intended use.

The Fitness-for-Service (FFS) assessment provides a quantitative measure of structural integrity and is part of asset integrity management. The assessments are used to highlight the need for replacement or repair of assets/components.

Two of the most commonly used are the recommended practice for assessing fitness-for-service published by the American Petroleum Institute (API) in API 579 and the guidance for the assessment of defects metallic structures published by British Standards in BS 7910.

Introduction to Finite Elements in Engineering

2002

This Book outlines the following topics: Chapter 1 gives a brief historical background and develops the fundamental concepts. Equations of equilibrium, stress-strain relations, strain displacement relations, and the principles of potential energy are reviewed

Properties of matrices and determinants are reviewed in Chapter 2.

Chapter 3 develops the key concepts of finite element formulation by considering one-dimensional problems

Finite element formulation for plane and three-dimensional trusses is developed in Chapter 4

Chapter 5 introduces the finite element formulation for two-dimensional plane stress and plane strain problems using constant strain triangle (CST) elements.

Chapter 6 treats the modeling aspects axisymmetric solids subjected to axisymmetric loading

Chapter 7 introduces the concepts of isoparametric quadrilateral and higher order elements and numerical integration using Gaussian quadrature. Beams and application of Hermite shape functions are presented in Chapter 8.

Chapter 9 presents three-dimensional stress analysis. Tetrahedral and hexahedral elements are presented.

Scalar field problems are treated in detail in Chapter 10. Chapter 11 introduces dynamic considerations. Preprocessing and postprocessing concepts are developed in Chapter 12

Observations on flaw Tolerance and brittle Fracture - The Effect of Post weld Heat Treatment

2018

This article summarizes aspects of recently published Reference [2], where a rigorous approach to generate impact test exemption curves and to determine appropriate Charpy impact test temperatures by establishing separate as welded and PWHT curves is presented. This approach permits direct comparison of flaw tolerance for as-welded and PWHT components using the Fracture Toughness Master Curve (Master Curve)
