Finite Element Modeling of Natural Gas Pipeline Structure in Response to External Loads

Abstract:

Experimental and Theoretical studies on Pipeline all reveal important difficulties in data interpretation. This paper proposes 3-D dynamic finite element (3-DDFE) model based on the digital data set from the Natural Gas Pipeline section. The analysis was constructed to demonstrate the effectiveness of the 3-DDFE model as a potential Pipeline fracture investigatory technique. A three-dimensional mesh generation technique is developed in this paper. Problems arising due to interactive modeling are highlighted in relation to complex geometries. A preprocessor finite element grid generator. FEMGEN has been modified for mesh generation. The modified FEMGEN program is linked with a three dimensional finite element program. Pipe sample is chosen to describe the flexibility and capability of the modified FEMGEN program. The appendix I shows typical subroutines to support the computer program discussed in the paper. The 3-DDFE analysis of Natural Gas Pipeline would allow the assessment of the fractures effects of different impact conditions and enable the development of enhanced Pipeline fracture and protection criteria for Natural Gas Pipeline.
