Abstract
Resistance Element Welding (REW) is a novel processing technology developed to join dissimilar materials such as aluminum and steel. It uses an auxiliary steel rivet (element) inserted into an aluminum sheet that forms a resistance spot weld with the steel sheet, and the aluminum work piece is mechanically joined by.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.6.381
Abstract
A study on shape optimization of a hot-stamped automotive door impact beam for lightweight design and improved crash performance was conducted using a static collision analysis based on FMVSS 214. An integral type one-piece door impact beam of bracket parts and pipe was realized using hot stamping technology. The method.....

2017;55(4):232-239. Published online 2017 Apr 6
DOI:
https://doi.org/10.3365/KJMM.2017.55.4.232
Abstract
To improve the sensitivity of impact sensor modules for automotive air bag systems, we developed a flexible module. The impact sensor was soldered with Sn-3.0Ag-0.5Cu (SAC305) solder on a flexible printed circuit board (FPCB) with an organic solderability preservative (OSP) surface finish. Thermal shock (TS) is one of the test.....
