The Finite Element Method (FEM) is today a commonly used aid in all product development activities.
Although FE analyses have been carried out during the last 30 years and the method has become a highly effective tool for stress and strain analyses, it is still difficult to find guidelines in the literature how to build modeIs and how to interpret the results from FE modeIs of welded, fatigue-Ioaded structures.
This guide focuses on possible problems and suggests either methods to avoid them or ways to deal with them.The guide describes and compares a number of different ways to model welded joints using sheII or solid elements. Several evaluation methods, such as the Hot Spot stress approach, the Nominal Stress method and the Effective Notch stress method are examined and compared.
The ambition has been to give practical advices and suggestions how to build FE models and how to interpret the results so that regular design codes can be used for weld assessment.
A number of different design codes are compared. The guide also includes a number of enlightening examples.
