Project Number | 37 |
Date of Summary | June 30, 1985 |
Subject | Structural Materials for Arctic Operations |
Performing Activity | National Bureau of Standards, Center for Materials Sciences |
Principal Investigator | Dr. Harry McHenry |
Contracting Agency | Minerals Management Service |
Estimated Completion | Complete |
Description | The objective was to study the potentially hazardous effects of Arctic (cold weather) operations on the integrity of steel weldments for Arctic structures. Fracture toughness of steel weldments are being investigated to determine requirements for verifying structural integrity. |
Progress | Complete. Fracture toughness tests were completed on five different geometrical crack configurations. Tests were conducted to determine the effects of different crack depths to specimen width ratios and to different crack depths to thickness ratios. Temperatures were varied from -120oC to room temperature. |
