Developed Surface

The punching severe deformation is a recently developed surface treatment that forms alloying by inducing a greater compressive equivalent stress field. Despite its proven utility, there has been little attention devoted to the accurate modeling of this process. In this work, a 3D-DEFORM finite element analysis was used to model the equivalent stress distribution induced by the punching process on a low-carbon steel surface. A majority of the controlling parameters of the process were taken into account. The effect of punching number, punching tip size, punching velocity and punching pressure on the equivalent stress distribution was evaluated. The results show that an equivalent stress distribution much higher than the conventional surface severe deformation can be obtained by optimizing the punching severe deformation process. The reported simulation results can successfully predict the punching severe deformation used to create an alloying layer on the surface of low-carbon steel.

Cargo hose tower is an alternative equipment that can be used in loading-unloadingprocess in oil tanker. This paper describes a structural safety analysis of cargo hose tower that transferoil to and from tankers or cargo vessels. Stresses for two types of load conditions that wereconsidered in this study and were drawn by finite element analysis. The results of the finite elementanalysis was also compared with the allowable stresses required in order to determine the designappropriateness of the cargo hose tower structure.
