This paper reports on research to optimize the connection pad assembly design for different types of loading conditions, which means minimizing the stresses in the wet welds and maximizing the energy absorption of the connection pad. The tubular geometry of the connection pad does not allow stress field analysis by the traditional strength-of-materials method. The authors discuss how, using the finite element method to analyze the stress contributions and the energy absorbed by the pad, the optimum pad dimensions could be determined for different types of loads.
