| Estimated Completion |

| 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. |
