| Description |
The objective was to develop and
evaluate the response of a stiff biaxial stress sensor in ice and permafrost under
different loading conditions. Recommendations will be made on future designs and uses of
the sensor in materials exhibiting time dependant mechanical properties. The sensor has a
low thermal sensitivity and is not affected by differential thermal expansion between ice
and gauge or ice creep. To provide a means for reliable, inexpensive ice stress
measurements which are needed to understand ice related problems. These include: ice loads
on marine structures; ice forces associated with ice drift, ride up, pile up, and pressure
ridge formation; thermal ice pressures. and the stress distribution under structures built
on permafrost. This project is an adjunct study to Project Nos. 40
and 43. |
