Thermal Crack Creation Process in an Automotive Brake Disk
자동차 브레이크 디스크의 열 균열 생성
Abstract
This describes thermal crack creation process in automotive disks. Thermal cracks have been serious defects which induced disastrous accidents during traveling. The thermal cracks must be regularly eye-inspected. The cracks have been experimentally analysed; but they were not reported by analytic means yet. This paper proposed thermal crack creation process by a computer simulation which enlightened how to investigate thermal crack by cheap means. We explained the disk thermal crack creation and calculated stress intensity factor of an assumed surface crack in an automotive disk.
