DROP WEIGHT TOWER FOR CRACK INITIATION IN FRACTURE MECHANICS SAMPLES |
摘要 |
Drop-weight tower (110) for reproducibly initiating a crack in a material sample for fracture mechanics testing comprising a base (120) with a top surface upon which a sample holder (124) is mounted to grip a material sample, an attachment column (140) having a linear rail (142), a carriage (162) attached to the linear rail (142) and a stage (164) is attached to the carriage. The stage (164) includes a vertical rod (184) and a razor-blade holder (178). A weight is slidably mounted to the vertical rod (184). The carriage is used to adjust the height of the stage (164) relative to the material sample. A hammer (180) slides up and down the vertical rod (184) to apply consistent and reproducible force on the razor (178) that then initiates the crack in the material sample. |
