Structural Mechanics and Computation

 

We use computational models to predict mechanical structural behaviour and to integrate information supplied from sensors and monitoring for real-time modelling.


 

Problems that we solve

Our overall goal is to ensure the long-term stability of onshore and offshore structures in remote locations through improvements to safety and productivity, including tunnels, underground mines, and petroleum or geothermal operations.

Our expertise is in developing new computer programming based on:

  1. Efficient meshless methods that allow rapid model building and parallelisation suitable for Graphics Processor Units (GPUs) using off-the-shelf-computers.
  2. Achieving real-time computational speeds for highly non-linear models with at least 100,000 degrees of freedom (DOF) using commodity computing hardware systems.
  3. Simplified models for cases when model parameters and input data cannot be accurately determined, as in the case of deformation and fluid flow computations in the earth’s crust, where the measurements are sparse and inaccurate. This allows real-time engineering computations, making analysis possible to every engineer’s desktop, which is especially important in remote monitoring and operation.  

We are also developing new methods for remote measurements and their interpretation – an area that has considerable impact in geomechanics design and monitoring and remote monitoring. Our team of researchers have demonstrated knowledge in the following areas:

  • Mechanics and dynamics of instability and failure
  • Mechanics and dynamics of fragmented solids and interlocking
  • New monitoring techniques and methods of measurement
  • Efficient and accurate algorithms for solving non-linear and non-classical models
  • New ultra-fast computational methods based on multiple GPUs.
