Static Stress Modelling
STATIC STRESS MODELLING
Our modelling services are based on the Integrated Static Stress Model (ISSM). ISSM is our own implementation of the indirect boundary element method. It models the rock mass as a linear elastic continuum but can also model the following non-linear behaviour:
- Preventing complete closure of tabular excavations
- Effect of backfill
- Ride on structures
It is 5X faster than similar commercial tools and has been multi-threaded to take advantage of multi-core computers. We offer routine modelling services as well as consultancy based on ISSM. Using our routine modelling services ensures that you have an up-to-date model of your mine which can then be used for planning, back analysis and special investigations. IMS will update and solve models on a daily, weekly or monthly basis. The customer can then use this solution together with a plugin to our Vantage visualization package to calculate and analyze stress, strain or derived parameters anywhere on the mine.
