얇은 판 구조물의 비등각 접촉 해석

Studied are the deformation shape and the traction of a thin strip structure, which is in contact with a rigid cylinder. Finite element (FE) analysis is carried out to investigate the change in shape and traction during the increase of the load using the code, ABAQUS. It is found that the traction begins with Hertzian profile as the load is applied, and is changed to have the similar shape induced by the rounded punch as the load increases. This implies that the contact shape should be carefully investigated even in the period of the load increase for correct contact analysis. The analytical solution in the case of the contact with rounded punch is also discussed with the FE result.
