Comparative study of conventional and hydromechanical deep drawing processes based on finite element analysis

Fracture and Structural Integrity, 2019
A two-dimensional finite element analysis has been performed to investigate hydromechanical and conventional deep drawing processes. The effects of the fluid structure interaction on the material formability, the strain and the thickness distributions ...

Automated Evaluation of Conventional Clock-Drawing Test Using Deep Neural Network: Potential as a Mass Screening Tool to Detect Individuals With Cognitive Decline

Frontiers in Neurology, 2022
IntroductionThe Clock-Drawing Test (CDT) is a simple cognitive tool to examine multiple domains of cognition including executive function. We aimed to build a CDT-based deep neural network (DNN) model using data from a large cohort of older adults, to ...

A sustainable hybrid FEA–AI optimization framework for multistage deep drawing of unidirectionally rolled copper micro-cups [PDF]

Scientific Reports
Precision micro-cups for electronic and medical applications require stringent control of resultant tool force (RTF) and spring-back (SB) to prevent defects, excessive tool loading, and material waste.

Numerical and experimental investigation of dry deep drawing of aluminum alloys with conventional and coated tool surfaces

Procedia Engineering, 2017
Abstract The demand for light weight concepts in the automotive industry motivates a permanently increasing amount of aluminum alloys in the body in white. Aluminum alloys cause challenging tribological conditions in sheet metal forming due to their adhesion tendency towards tool steel.

Process-Integrated Lubrication in Sheet Metal Forming

Journal of Manufacturing and Materials Processing, 2022
The deep-drawability of a sheet metal blank is strongly influenced by the tribological conditions prevailing in a deep-drawing process. Therefore, new methods to influence the tribology represent an important research topic. In this work, the application
