The objective of the research reported in this paper is to investigate in depth the performance properties of the 5 1/2-in. 14-lb/ft J-55 API 8-round short thread casing connection under different load cases, via experimental tests and finite element analyses. The FEA models are validated by comparing the numerical results with full-scale tests. The validated models are afterwards used to perform parametric studies on the connection behavior.
