Abstract:
In this paper is investigated the analysis of stress and deformation fields of shape complex beams. The shape complex beams are made from load-bearing sheet (trapezoidal sheet) circumferentially connected with strips of sheet metal, these beams are a substitute for more complex and heavier beams. The numerical analysis with static load are performed for these beams. The effect of three different types of connections between load-bearing sheet and strips of sheet metal is investigated. The first type of connection is represented by the trapezoidal sheet perfectly welded to the strips of sheet m

Abstract:
The discrete clamp is used to replace the integral clamp in the traditional stretch forming process, and the stretch forming process of complex curved parts is studied. With the trapezoidal profile part and the double curved top part as the research objects, numerical simulation of the stretch forming process with the integral clamp and the discrete clamp is carried out respectively. The numerical simulation results show that: compared with the integral clamp, it is easier for the trapezoidal profile part to fit the die during stretch forming with the discrete clamp, and the distribution of st

Abstract:
Bending response of corrugated core metallic sandwich panels was studied experimentally under three-point bending loading. Two different core configurations were used: the corrugated monolithic core and the corrugated sliced core. The trapezoidal corrugated cores were manufactured from aluminum sheets via a sheet metal bending mould. After the sandwich panel samples were prepared, they were subjected to three-point bending tests. The load and displacement responses of the sandwich panels having different core configurations were obtained from the experimental testing. The influence of the core

Abstract:
Ultrasonic measurement is used to evaluate wrinkles during sheet metal forming. The authors developed a new apparatus for investigating the relationship between the wrinkles in press forming and the ultrasonic reflection characteristic of an angle beam. The new evaluation apparatus was composed of probe-fixing parts, an upper die, a middle die, and a lower die. A specimen was sandwiched by a pair of dies in the evaluation apparatus. Angle beam probes for transmission and reception were set on the upper die. Specimens in the form of plates having periodic trapezoidal wrinkles were fabricated by

Abstract:
Springback will occur when the external force is removed after bending process in sheet metal forming. This paper proposed an adaptive-network-based fuzzy inference system (ANFIS) model for prediction the springback angle of the SPCC material after U-bending. Three parameters were selected as the main factors of affecting the springback after bending, including the die clearance, the punch radius, and the die radius. The training data were obtained from results of U-bending experiment. The training data with four different membership functions – triangular, trapezoidal, bell, and Gaussian func

Abstract:
Solid shell element models which possess only translational degrees of freedom and are applicable to thin structure analyses has drawn much attention in recent years and presented good prospect in sheet metal forming. In this study, a solid shell element model is introduced into the dynamic explicit elastic-plastic finite element method. The plane stress constitutive relation is assumed to relieve the thickness locking and the selected reduced integration method is used to overcome volumetric locking. The assumed natural strain method is adopted to resolve shear locking and trapezoidal locking

Abstract:
This paper investigates the effects of different channel geometries on the performance of Proton Exchange Membrane Fuel Cells (PEMFCs). The study employs computational fluid dynamics (CFD) coupled with thermal and electrochemical simulations to analyze five channel geometries (cases A to E) of bipolar plates. A thorough study on this topic is not found in the literature and aims to identify designs that optimize performance and align with cost-effective production methods. Among the various studied geometries, case D, featuring a trapezoidal cross-section, exhibited the most favorable performa

Abstract:
Composite metal decking has become one of the prevalent forms of Fast Track Construction for multi-story steel buildings. The in-plane stiffness of composite metal decks however is of considerable importance as they typically act as a diaphragm in lateral-load- resisting systems and thus attract a large in-plane shear. The diaphragm action or the in-plane shear capacity of composite metal decks remained a concern for structural engineers and designers. The present work aims to investigate the in-plane shear behavior of fiber reinforced composite metal decks and compare it to that reinforced wi

Abstract. Aluminum Lithium alloys are recuperating substantial interest from automotive and aerospace industries owing to their extraordinary specific strength as compared to conventional aluminum (2xxx, 6xxx, and 7xxx) alloys. The goal of the present investigation is to study AA 8090 joints produced with the unique solid-state welding technique friction stir welding (FSW). Tool pin profile induces remarkable influence on friction and further plastic deformation during FSW. Therefrom, the influences of three distinct but constant dynamic area conditioned tool pin geometries namely, square trap
