Abstract:
Tailored blanks with different blank thicknesses are semi-finished parts that can be used to produce stamping parts having a real tailor-made solution. This study investigates a manufacturing process that can produce a tailored rolled blanks(TRB) having variable thickness variations both in longitudinal and width directions. The process was experimentally and numerically investigated using three types of the conventional blank and blanks having circular and square holes. To characterize the process, the deformation behaviors of blanks were intensively analyzed. In order to understand the effec

Abstract:
This work deals with the design of the thickness of an AZ31 alloy blank, which is a superplastic magnesium material, to manufacture a hemisphere with a uniform final thickness. The finite element technique was used for the design process. The superplastic free-forming manufacturing was simulated for a part whose initial thicknesses were made to vary through two independent design parameters to obtain a linear thickness decrease from the pole to the end of the blank to form. This is because a linear thickness decrease is easily obtained through a machining process. The optimized blank, that is,

In this study, the springback law of generatrix direction, circumferential direction of tailor welded blanks (TWBs) cylinder shallow shell impact from blank holder force, punch profile radius and sheet thickness was researched by finite element analysis, which was compared with non-welded blanks. The results show that: in the circumferential direction, with the increase of blank holder force, the trimming springback of the tailor welded blank of the thickness combination of 1.2mm and 0.8mm (TWB1208) is decreased firstly and then increased, which is larger than that of the non-welded blanks of

Abstract:
Deep drawing of square boxes of tailor-welded blanks (TWBs) was studied by experiment and simulation in this paper. When the tailor-welded square boxes with different thickness was drawn to square boxes, the weld seam moved towards the thick part on the bottom and towards the thin part on the wall of square boxes. If the blank-holder force was very small, the wrinkling will happen on the thin part. If the blank-holder was very large, fracture will occur on thin part. Draw beads and non-uniform blank-holder force were investigated to control the deformation of the TWBs workpieces in this paper.

In this article the flanging method of thin-walled ring blanks using the elastic punch and rigid die scheme is investigated. Presence of a cylindrical portion near the larger edge and a flat area at the side of the blank hole is mandatory. Such conditions allow producing conical parts with minimal thickness variation by altering height of the cylindrical portion. Conducted experimental studies showed that the minimal thickness variation values are not exceeding 16% for different materials and relative thicknesses less than 0,01.

Springback is one of the main quality defects in the sheet forming. In this paper, numerical simulation is used to analyze the effects of blank holder force, friction coefficient, blank thickness, die corner radius and stroke on springback. The effect of blank holder force and blank thickness on springback is obvious. Springback decreases as the BHF and blank thickness increase. Increasing friction coefficient between tools and blank shows a good suppression effect on springback. Larger die corners increase the curvature of side wall and worsen the springback, but the springback of flange is r

Abstract:
Deep drawing is one of the very old and widely practiced processes in the sheet metal industries for producing beverage cans and automobile components. Many of the deep drawn components need multiple draws to achieve the required dimensions, because often it is not possible to obtain the desired reduction in the first draw. Among several defects that occur during the process, earing is one of the prominent and common defect. In the present work, analysis has been carried out by dividing the total deformation region into several zones. Analysis of each zone is carried out by proposing kinematic

Abstract:
The newly developed element exchange method (EEM) for topology optimization is applied to the problem of blank shape optimization for the sheet-forming process. EEM uses a series of stochastic operations guided by the structural response of the model to switch solid and void elements in a given domain to minimize the objective function while maintaining the specified volume fraction. In application of EEM to blank optimization, a sheet forming simulation model is developed using Abaqus/Explicit. With the goal of minimizing the variability in wall thickness of the formed component, a subset of

Abstract:
Abstract. This paper describes a study of thinning and forming force in multi-stage single point incremental forming. Four process parameters namely pitch, tool diameter, blank thickness and initial draw angle are considered to study their influence on maximum thinning and peak forming force. Experiments are designed using face-centered composite design (CCD). Experimental results are analyzed using analysis of variance (ANOVA). It is found that initial draw angle is the most influencing parameter for maximum thinning, while peak forming force is most influenced by blank thickness. Maximum thi

Abstract:
We collected ∼1300 km of ground-penetrating radar profiles over McMurdo Ice Shelf, Antarctica, using frequencies between 40 and 400 MHz to determine extent, continuity and depth to the brine. We also used profiles to determine meteoric ice thickness and locate englacial features, which may suggest ice shelf instability. The brine extends 9–13 km inland from the ice shelf terminus and covers the entire region between Ross, White and Black Islands. Jump unconformities and basal fractures exist in the brine and ice shelf, respectively, suggesting prior fracturing and re-suturing. One 100 MHz prof
