① 실험목적
creep test를 통해 피로시험(동하중)과 creep(정하중)의 차이를 이해하고, creep test의 원리를 이해할 수 있으며, 탄성구간에서도 재료에 힘을 반복적으로 가하면 파괴됨을 알고, 제품 설계시 이를 적용할 수 있다.

② 실험이론
◆ Elasticity and Plasticity (or Elastic and Plastic Deformation)
When a material is stressed so that it deforms, then returns to its original shape when the stress is removed, the material is perfectly elastic. The atoms in the material have not moved, but the bonds between them have stretched, then returned to their original position.

① Accurately measure and record the width and thickness of the specimen.
② Put the weight hanger in position and fit its support pin in its highest hole to hold the arm up and ready for the test specimen.
③ Fit the steel specimen support clips to the specimen.
④ Fit the specimen into place between the black support block and the arm, and fit the pins.
⑤ Put the transparent cover into place around the specimen. Make sure that the thermometer is in its hole in the top of the cover and its tip is near to the specimen. Wait for at least five minutes for the temperature reading to stabilize, and then record the temperature around the specimen.
