Fatigue studies on carbon steel piping welded materials and its connections

In this study, the fatigue characteristics in pipe is investigated to increase the knowledge of the fatigue crack growth in pipe. The material used in this study is carbon steel. This study does a simulation of the fatigue crack growth on a created model. This simulation uses a software called ABAQUS, this software uses extended finite element analysis as a platform to simulate the changes happen to the model when in different condition. This simulation require the construction of a 2-D model that will be experiencing fatigue crack growth. This means the model will be subjected to the force of tensile and compression to imitate what happen during the life of a pipe. The model will undergoes several steps before result can be obtained. For example, the mechanical properties data must be inputted in the software before running the software. The steps also included other steps such as load assignation and meshing. The obtained result comes in form of images of the crack opening after the condition applied. It shows the different results based on the condition that the model have gone through.
