Modeling of the minimum variable blank holder force based on forming limit diagram (FLD) in deep drawing process

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
This paper presents the mathematical approach of minimum blank holder force to prevent wrinkling in deep drawing process of the cylindrical cup. Based on the maximum of minor-major strain ratio, the slab method was applied to determine the modeling of minimum variable blank holder force (VBHF) and it compared to FE simulation. The Tin steel sheet of T4-

A Triaxial Failure Diagram to predict the forming limit of 3D sheet metal parts subjected to multiaxial stresses [PDF]

open access: yes, 2016
Accurate prediction of failure and forming limits is essential when modelling sheet metal forming processes. Since traditional Forming Limit Curves (FLCs) are not valid for materials subjected to triaxial loading, a new failure criterion is proposed in ...

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]

open access: yes, 2009
In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

Real‐time quality and safety monitoring of fruit juice using paper‐based platform

open access: yesFood Biomacromolecules, EarlyView.
Schematic illustration of a paper‐based biosensor for rapid detection of fruit juice spoilage. Abstract Food spoilage and safety concerns still remain critically challenging within the fruit juice industry, especially as conventional detection methods, though precise, are often too time‐consuming, costly, and reliant on centralized laboratories.

Experimental and Numerical Investigations of Deep Drawability of AA1200 [PDF]

open access: yes, 2016
The ability of a sheet metal to be formed in a given process without failure is known as formability. Formability is a measure of the amount of deformation a material can withstand prior to fracture or excessive thinning. Forming Limit Diagram (FLD) is a

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.
