Towards better finite element modelling of elastic recovery in sheet metal forming of advanced high strength steel [PDF]

, 2011
The first part of this study discusses the influence of element type on parameters such as accuracy of the FE simulation, simulation time and convergence. Guidelines on optimal implementation of element types are proposed.

New Multiphase CP and DP 1000 MPa strength level grades for improved performance after hot forming [PDF]

, 2019
Pure martensitic steels have after hot forming limited performance in terms of rest ductility which limits the application in crash relevant parts. New steel grades were designed in the EU project HOTFORM including the corresponding process routes. These

Denoising Diffusion Model With Pixel‐Adaptive Convolutions for Sheet Metal Forming Analysis

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Traditional tool development processes in mechanical forming, especially for pressing tools, are often limited by time‐consuming trial‐and‐error cycles, which rely heavily on expert knowledge. These cycles can create bottlenecks and increase costs.

Compensation of deep drawing tools for springback and tool-deformation [PDF]

, 2008
Manual tool reworking is one of the most time-consuming stages in the\ud preparation of a deep drawing process. Finite Elements (FE) analyses are now widely\ud applied to test the feasibility of the forming process, and with the increasing accuracy of ...

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...

A novel indicator for kinematic hardening effect quantification in deep drawing simulation [PDF]

, 2019
Deep drawing simulation techniques reduce tool design costs and improve tool performance and reliability. In terms of strain hardening, mixed models capturing the kinematic effect are sometimes more accurate than isotropic models.

Dry‐Processed Graphite Electrodes Enabling Ultra‐High Areal Capacity and Stable Fast‐Charging Performance

Carbon Energy, Volume 8, Issue 4, April 2026.
A robust fibrillated network formed by high‐molecular‐weight PTFE enables uniform Li+ flux and plating‐free behavior in dry‐processed graphite anodes, achieving ultra‐thick electrodes (10 mAh cm−2 as representative, extended to 30 mAh cm−2) with high volumetric energy density and stable full‐cell performance.

Grain Size Effects and Multi‐Stage Optimization in Sustainable Micro‐Deep Drawing of Copper Cups: An FEA and Experimental Study

Engineering Reports, Volume 8, Issue 1, January 2026.
Process flow. ABSTRACT The demand for miniaturized metallic components in electronics, biomedical devices, and aerospace necessitates sustainable micro‐forming solutions. Conventional deep‐drawing often suffers from stage complexity, excessive die use, and size‐effect limitations.
