Experimental and numerical study of micro deep drawing
MATEC Web of Conferences, 2015 Micro forming is a key technology for an industrial miniaturisation trend, and micro deep drawing (MDD) is a typical micro forming method. It has great advantages comparing to other micro manufacturing methods, such as net forming ability, mass ...

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Using the solid-shell element to model the roll forming of large radii profiles [PDF]
, 2012 Roll forming is an incremental bending process for forming metal sheet, strip or coiled stock. Although Finite Element Analysis (FEA) is a standard tool for metal forming simulation, it is only now being increasingly used for the analysis of the roll ...

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Pulsed magnetic forming of the magnesium alloy AZ31 – Comparison to quasi-static forming [PDF]
, 2012 Magnesium alloy AZ31 metal sheets were formed at room temperature with a pulsed magnetic field induced by a flat coil. For this a die with variable die radius and inside diameter was used.
