DFT Study of Planar Boron Sheets: A New Template for Hydrogen Storage [PDF]

, 2009
We study the hydrogen storage properties of planar boron sheets and compare them to those of graphene. The binding of molecular hydrogen to the boron sheet (0.05 eV) is stronger than that to graphene. We find that dispersion of alkali metal (AM = Li, Na,

The Forming Limit Diagram of 2A16 Aluminum Alloy Sheet Based on Hydraulic Bulging Test of Elliptical Die [PDF]

MATEC Web of Conferences
An elliptical die hydraulic bulging test was carried out to explore the forming performance of 2A16 aluminum alloy sheets during hydroforming. By using five groups of elliptical dies with ovality of 1.0, 0.9, 0.8, 0.6, and 0.4, the effects of different ...

Tolerancing and Sheet Bending in Small Batch Part Manufacturing [PDF]

, 1994
Tolerances indicate geometrical limits between which a component is expected to perform its function adequately. They are used for instance for set-up selection in process planning and for inspection.

Selection of Constitutive Material Model for the Finite Element Simulation of Pressure-Assisted Single-Point Incremental Forming

Machines, 2022
Pressure-assisted single-point incremental forming (PA-SPIF) is one of the emerging forming techniques for sheet metals that have been the subject of rigorous research over the past two decades. Understanding of its forming mechanisms and capabilities is

Effect of Microstructures on Yield Strength in Hot-Stamped Steel Sheet

MATEC Web of Conferences, 2015
For automotive structural parts, hot stamping is being increasingly used because of the need for both higher fuel efficiency and crashworthiness. The yield strength of hot-stamped steel sheet is lower than that of water-quenched steel sheet.

Influence of the Drece Process of Severe Plastic Deformation on the Mechanical Properties of the Ultra-Low Carbon Interstitial Free Steel [PDF]

Archives of Metallurgy and Materials, 2018
This research paper shows the influence of a repeated SPD (Severe Plastic Deformation) plastic forming with the DRECE technique (Dual Rolls Equal Channel Extrusion) on hardening of low carbon IF steel. The influence of number of passes through the device

Optimization of the Sheet Metal Base of a Toggle Clamp Using Finite Element Method

International Journal of Engineering and Management Sciences, 2021
Optimization relates to the ultimate yield strength and the maximum stress incident on the current model under critical working conditions and finds through iterative processing a way to compensate for the strength requirement without going beyond the ...

A New Approach for Obtaining the Compression Behavior of Anisotropic Sheet Metals Applicable to a Wide Range of Test Conditions

Metals, 2020
The consideration of anisotropic and asymmetric tension-compression behaviour in some materials has proved to be of great importance for the modelling of plastic behaviours that allow for accurate results in sheet metal forming analysis.
