Comparison between incremental deformation theory and flow rule to simulate sheet-metal forming processes [PDF]

, 2012
Numerical simulation of the deep drawing process for the manufacture of aeronautical or automotive components should predict with good accuracy the behaviour during the forming operation, taking into account, the material and the process parameters ...

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Fracture-Based Formability Prediction in Incremental Forming

, 2010
In recent years considerable research has been done in incremental forming due to its greater process flexibility and higher forming limits. In incremental forming the formability depends to a great extent on the toolpath via the incremental depth being ...

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer

Molecular Oncology, EarlyView.
New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

An investigation of multi-pass incremental sheet forming [PDF]

MATEC Web of Conferences
This study investigates toolpath strategies of multi-pass incremental sheet forming (MSPIF) including a combination of an IN (I) pass where the tool moves inwards and downwards and an OUT (O) pass where the tool moves outward and upward. MSPIF processes (

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

A Comparative Investigation of Conventional and Hammering-Assisted Incremental Sheet Forming Processes for AA1050 H14 Sheets

Metals, 2021
Incremental Sheet Forming (ISF) is emerging as one of the popular dieless forming processes for the small-sized batch production of sheet metal components. However, the parts formed by the ISF process suffer from poor surface finish, geometric inaccuracy,

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Investigations on the Formability of Incremental Punching Process

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011
It was reported that the incremental sheet metal forming (ISMF) produces larger deformations as compared to the conventional forming processes. We developed a new ISMF method based on incremental punching. In this study, a theoretical method based on M-K
