“…Among others, a number of studies have been conducted on ULS-based design, technique, and its applications in terms of ULS application to stiffened panels [36][37][38][39], scaling effect [40,41], stiffened panels with opening [42], dynamic ULS [43], low temperature effect [14], and prediction of ULS by an artificial neural network (ANN) [44]. The FLS of an offshore riser by an ANN and simplified method [45,46], the ALS and ULS of a non-ice class aged ship [4,47], a steel plated structure [3], a ship's hull [2], and Floating Liquefied Natural Gas (FLNG) [48,49] are also investigated.…”

“…In particular, the finite element method (FEM), one of the famous numerical methods, is considered a powerful technique for solving issues in various fields, such as engineering and medical. Moreover, the computational fluid dynamics (CFD)-based and fluid-structure interaction (FSI)-based numerical simulations are also getting more and more popular in structural design, following the development of computer technology [4].

This research aims to study the ultimate limit state (ULS) behaviour of stiffened panel under longitudinal compression by a non-linear finite element method (NLFEM). There are different types of stiffeners mainly being used in shipbuilding, i.e., T-bar, flat-bar, and angle-bar. However, this research focuses on the ultimate compressive strength behaviour of flat-bar stiffened panel. A total of 420 reliable scenarios of flat-bar stiffened panel were selected for numerical simulation by the ANSYS NLFEM. The ultimate strength behaviours obtained were used as data for the development of closed form shape empirical formulation. Recently, our group proposed an advanced empirical formulation for T-bar stiffened panel, and the applicability of the proposed formulation to flat-bar stiffened panel is confirmed by this study. The accuracy of the empirical formulation obtained for flat-bar stiffened panel was validated by finite element (FE) simulation results of statistical analysis (R2 = 0.9435). The outcome obtained will be useful for ship structural designers in predicting the ultimate strength performance of flat-bar type stiffened panel under longitudinal compression.

“…From a geometrical point of view, the friction occurs between rollers-workpiece, plug-workpiece, and guiding tool-workpiece interfaces [9]. From a manufacturing point of view, the friction between rollers and workpieces is the most important, because it is responsible for introducing power and movement into the system, and the contact area between rollers and billet is higher than other areas [10]. In this case, the piercing plug is freely rotating on its axis, and just the friction resistance in the piercing direction is important.…”

During the hot piercing phase of seamless tube production, friction and contact conditions between tools and workpiece significantly influence final product quality and energy consumption. The friction effects on the production of high alloyed steels like Super Cr13 steel are critical. This study analyses the effect of different friction conditions at the workpiece-tool interface in the piercing of Super Cr13 steel bars to minimize total energy consumption in such a manufacturing process. For this purpose, a three-dimensional finite element method (FEM) is employed to simulate and analyze the piercing process. The variety of tools (plunge, rollers, and Diescher disks) and contact conditions lead to differences in the applied stress at different workpiece areas. Consequently, various friction models and friction coefficients were selected for different interfaces. The relation between strain rate, temperature, and geometry of pierced tube are discussed, and the selected friction relation with total power and energy consumption is presented. Experimental tests have been used for FEM validation and result analysis, and finally, the most effective conditions with lower total energy consumption are presented.

“…Due to the nature of the process, the interaction effects of solid and fluid are necessary to investigate. Therefore, Topa et al 15,16 utilized the fluid-solid interaction for the numerical solution of the piercing process. In this way, they carried out the ALE method for simulation via the FSI approach.…”

The rotary tube piercing (RTP) is the first process of making the seamless tube after producing the desired alloy ingot. There are several approaches to manufacture a seamless tube, but one of the most common types is RTP. This approach covers a wide range of processes that are categorized according to the number and shape of the rollers. On the other hand, each of these types has designed guides in the output and input of the piercing process. In this paper, a new design of the input guide for four types of rollers have been examined and simulated. Thus, four specimens including Diescher and Conical rollers were considered, with the different number of rollers. Results including torque, total force, mandrel wear, temperature distribution, and strain were extracted using FEM simulation. In order to the validation of simulation, the total force and oscillations of applied force within the process have been compared with the experimental results. The results obtained through this simulation, are more in line with the empirical results obtained from previous research. As well as, the FEM simulation confirmed the performance accuracy of the output and input guides of the RTP process. On the other hand, the results indicate that the three-roller Diescher type with 17° feed angle, has the most suitable arrangement for production of seamless tube.
