EXPERIMENTAL FLC DETERMINATION OF HIGH STRENGTH STEEL SHEET METAL

open access: yesActa Metallurgica Slovaca, 2015
To assess formability in sheet forming, experimentally determined Forming Limit Curves (FLC) are often used. These conventional FLCs represent the forming limits (i.e.

Development of a Pneumatic High Speed Nakajima Testing Device

open access: yes, 2012
Forming limit diagrams are an essential tool for describing the formability of sheet materials in the deep-drawing process. Here, the well known and frequently employed procedures are the Nakajima and the Marciniak-Tests. Whereas these procedures' standardisation is quite advanced in the quasi-static range, numerous different test procedures exist in ...

Study of the Formability of Laminated Lightweight Metallic Materials

open access: yesMATEC Web of Conferences, 2017
The main objective of this work was to test the formability of laminated materials. Laminated materials are considered a good choice when parts with reduced weight are considered. Thus, a laminated material, aluminum - polypropylene - aluminum (Al-PP-Al),

Intensive Endoscopic Resection for Downstaging of Superficial Non-ampullary Duodenal Epithelial Tumor Burden in Familial Adenomatous Polyposis: A Single-center Retrospective Study on Long-term Clinical Outcome. [PDF]

open access: yesDEN Open
ABSTRACT Background and Study Aims Familial adenomatous polyposis (FAP) is a genetic condition that increases the risk of developing colorectal polyposis and cancer, as well as superficial non‐ampullary duodenal epithelial tumors (SNADETs). In this single‐center retrospective study, we investigated the long‐term clinical outcomes of intensive ...

A dieless Nakajima test for additively deposited materials

open access: yesMaterials Research Proceedings
Abstract. This paper focuses on a novel Nakajima test for characterizing the formability of additively deposited materials without extracting sheet blanks. Material is deposited by wire-arc additive manufacturing in the form of ‘Π-shaped’ vertical walls, and the testing regions are then machined to the desired thickness and shapes for subsequent ...
