| Description |
The primary goal of this research project is to ensure the
availability of a validated software tool that can be used to predict the
response of polyester ropes under a variety of loading conditions. Such a
tool is needed to interpret and extend test data and to develop design
guidelines. Laboratory testing of large and full-scale ropes, while
essential for gauging performance, is expensive and time consuming.
Development of a reliable computer model has the potential to significantly
reduce the costs and time needed for experimental testing. |
| Progress |
Project completed. For most of the cases analyzed, the
proposed numerical model accurately predicts the capacity of the damaged
ropes, but the model overestimates the rope failure axial strain. |
