Correlation of tensile properties with plane-strain, limiting dome height
Journal of Applied Metalworking, 1984While no single test can predict the formability of sheet metal under all modes of deformation, the planestrain limiting dome height (LDH0) has been shown to correlate with material performance during stretching. However, because LDH0 values are a relatively new measure of formability, and require specialized equipment to measure, such data are not ...

Warm forming has some important advantages, the most significant being that forming limit strains increase at elevated temperatures. To quantify this advantage for an AA3003 brazing sheet, forming limit diagrams were determined using warm tooling developed to perform limiting dome height (LDH) experiments together with a digital image correlation (DIC)

The Limiting Dome Height Test for Assessing the Formability of Sheet Steel
SAE technical paper series, 1985<div class="htmlview paragraph">The Limiting Dome Height (LDH) test has attracted much interest as a simulative tool for predicting press performance of materials. However, problems of test reproducibility have been observed. An experimental evaluation has been performed to determine the possible source or sources of these problems.

This paper aims to study the effect of stress relieving on Limit Dome Height (LDH) of Ti-TWBs at elevated temperatures. This is achieved by developing a newly constructed heating system. The elevated temperature of the system can be varied and monitored by a separately control panel. All Ti-TWBs were prepared and used to examine the LDHs under elevated

Evaluating the GMR-Limiting Dome Height Test as a new measure of press formability near plane strain
Journal of Applied Metalworking, 1978A number of tests have been proposed as predictors of press shop formability. The most common of these are the Olsen cup, tensile, and hardness tests. However, none of these tests are very successful. Recently, A.K. Ghosh proposed the Limiting Dome Height test (LDH) to predict formability since this test modifies specimens to produce the same strain ...

Microstructure Evolution in Three FCC Materials During Limited Dome Height Test
2009AA 1050 Aluminium, AISI 304L and AISI 316L austenitic stainless steel were deformed at different strain and strain path. Deformed microstructure in AISI 304L and AISI 316L austenitic stainless steel shows significant amount of deformation twin and Strain Induced Martensite (SIM). AA 1050 Aluminium shows grain interaction between neighbouring grains. In

The objective of this present work is to the comparison of simulation and experimental results on the formability behaviour of dissimilar aluminium alloys such as AA6082-O, AA5083-O, AA5052-H32 and AA6082-T6 using limiting dome height (LDH) test. This research work is divided into four main parts.

Journal of Applied Mechanics, 1997
By combining the crystalline orientation distribution with a hardening evolution equation, a new elastic/crystalline viscoplastic material model is established. We focus our discussion on looking primarily at the texture effects on the strain localization of limit dome height (LDH) tests which are simulated using our Dynamic-Explicit finite element ...
