구형 충격을 받는 필름 코팅된 유리 시스템의 거동을 개발한 유한 요소 프로그램에 의하여 연 구하고자 한다. 충격 거동을 예측하기 위하여 Sun의 higher order beam theory와 Kurapati의 generalized power law와 연계한 새롭고 효과적인 동적 유한 요소법을 제안한다. 필름 코팅된 유리 시 스템과 모놀리식 유리에 대하여 접촉력, 변형량, 운동에너지, 속도 및 응력 등을 계산한 후 결과를 비교 검토하여 코팅 시스템의 필름이 충격 손상을 방지하고 충격 저항이 우수하다는 것을 정성적 및 정량적으로 규명하였다.

The wheel is an active area of automobile component design and development. The wheel must be durable enough to tolerate significant loads and harsh environment. Temporary tire substituted for spare tire is made in a half band wheel size. Therefore this temporary tire is carried out lightweight and fuel saving of automobile. In this research, structural analysis and fatigue analysis of the temporary steel wheel are carried out using ANSYS 3D-modeling. The model is verified by the equivalent(von-Mises) stress analysis obtained from the ANSYS static structural analysis. Fatigue analysis is performed at the equivalent stress considering the automobile load and moment. Finally, this temporary wheel can be used temporary but not continuously.

Obturator hernia is a rare case of pelvic hernia. It is important cause of small bowel obstruction in older wemen. It frequently occurs who has multiparous, skinny body, and old age. Patients presented with nausea, vomiting, and abdominal pain. Most common symptom is a strangulation combined with mechanical intestinal obstruction.
