Experimental and Numerical Investigations into the Failure Mechanisms of TRIP700 Steel Sheets

Metals, 2018
The formability and failure behavior of transformation-induced plasticity (TRIP) steel blanks were investigated through various stress states. The forming limit diagram (FLD) at fracture was constructed both experimentally and numerically.

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

IOP 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-

Obtaining Forming Limit Diagram Using OpenCV [PDF]

한국정밀공학회지
The 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 ...

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 ...

Modelling and evaluation of the post-hardness and forming limit diagram in the single point incremental hole flanging (SPIHF) process using ANN, FEM and experimental

Results in Engineering, 2023
In the single point incremental hole flanging (SPIHF) process, a sheet material with pre-cut holes is deformed using the SPIF technique to generate a flange, making it an effective approach for low volume manufacturing and quick prototyping.

Histone Modification Complex JMJ704‐HDA709 Negatively Regulates Salinity Tolerance in Rice

Advanced Science, EarlyView.
This study reveals that the rice histone demethylase JMJ704 interacts with HDA709―a H3K9ac deacetylase characterized herein―to form a chromatin‐modifying complex. Under salt stress, OsWRKY72 recruits this complex through interaction with JMJ704 to target loci, repressing the expression of oxidative stress and salt‐responsive genes via removal of ...

Discovery of an Antiviral Electron Transfer Process to Create Catalytically Self‐Sufficient Viral Restriction Factors

Angewandte Chemie International Edition, EarlyView.
CYB5R3 is identified as a putative electron‐transfer partner of viperin (RSAD2), explaining why ER localisation is required for antiviral activity. Its utilisation enabled the engineering of immune‐silent, catalytically self‐sufficient antiviral restriction factor enzymes (iCAREs) that produce an antiviral nucleoside triphosphate analogue (ANTA ...
