5d/6d Wilson loops from blowups
Journal of High Energy Physics, 2021 We generalize Nakajima-Yoshioka’s blowup formula to calculate the partition functions counting the spectrum of bound states to half-BPS Wilson loop operators in 5d (and 6d) supersymmetric field theories. The partition function in the presence of a Wilson

Metallographic Analysis of Nakajima Tests for the Evaluation of the Failure Developments
Procedia Engineering, 2017 Abstract The material characterisation in sheet metal forming is significantly improved with the introduction of optical measurement systems. The optical measurement is based on the digital image correlation (DIC) technique, which provides accurate strain measurement of the local strain distribution on specimens.

Obtaining Forming Limit Diagram Using OpenCV [PDF]
한국정밀공학회지The Forming Limit Diagram (FLD) is a criterion used to assess the formability of sheet metal during a manufacturing process. Traditionally, FLDs are obtained through manual measurements using Mylar tape or through the use of automatic deformation ...

Forming limit curves of ultra-thin sheet metal for high-speed Nakajima test
, 2022 Abstract This paper is concerned with Nakajima test and forming limit curve (FLC) of stainless 304 ultra-thin sheet metal in relation to the strain rate effect. The mechanical properties related to the micro structure of specimens are studied based on quasi static tension test. The forming limit curves are constructed by Nakajima tests with two

EXPERIMENTAL FLC DETERMINATION OF HIGH STRENGTH STEEL SHEET METAL
Acta 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.
