Rapid feasibility assessment of components to be formed through hot stamping: A deep learning approach

“…As mentioned by Zhou, Li & Xu [17], scalar based models lack informativeness due to this data consolidation. This is particularly true in scenarios where the manufacturing feasibility is determined by distribution based indicators, such as post form thickness gradients [18], surface slip lines [19] and wrinkle distributions [20]. To provide richer data representations, other references predicted full field data on a FE mesh using deep neural networks (DNNs).…”

Formability of aluminum 1050A at high temperatures: Numerical modeling and experimental validation

“…For all above material models as well as theoretical developments, computational schemes (Ahmad et al, 2019;Cherouat et al, 2018;Gassara et al, 2009;Gatea et al, 2017;Hu et al, 2018;Robert et al, 2012;Zheng et al, 2017;Zhuang et al, 2016) were proposed including inverse identification methods, advanced Finite Element formulations, Latin American Journal of Solids and Structures, 2021, 18(5), e385 3/21 optimization schemes, implemented integration algorithms using various computing tools (Abaqus/Explicit© finite element code/UMAT, VUMAT subroutines, combined programming language/numerical tools (Python, Fortran, Matlab,…). For the implementation cost, the schemes require computational time (algorithm development, CPU time) respective of the formulated approach's variables number.…”

An Investigation of the Effects of a Sheet Material Type and Thickness Selection on Formability in the Production of the Engine Oil Pan with the Deep Drawing Method

“…Cheng et al conducted a study with the aim of eliminating wrinklings that occurred as a result of deep drawing in materials to increase lightness and vibration removal performance in automotive applications [18]. In the literature, there are analytical [19,20] and experimental [21][22][23] studies in which the change of product thickness as a result of deep drawing with the increase in the deep drawing ratio and height of metal sheets is investigated.…”
