Karen joined Itasca Australia in 2017, and with a background in marketing and process improvement, she provides administration support to the team and manages software sales for the region.
This webinar is for people who have used 3DEC before and are interested in the latest developments.
This hands-on, virtual training course is 16 hours total, spread over four days in a 1.5-week period, and covers the analysis of embankment dams using FLAC.
Mr Lachenicht has 25 years’ experience in mining geomechanics ranging from consulting, research projects, studies to mine operational experience. Over the course of his experience, positions held include manager, senior geotechnical engineer, geotechnical superintendent and principal geotechnical engineer roles with associated levels of responsibility.
Since 2001, Itasca has been a member of the Hybrid Stress Blast Model (HSBM) project with the goal of developing a numerical model of the rock blasting process. The software created by Itasca, called Blo-Up, uses a unique combination of continuous and discontinuous numerical methods to represent the key processes occurring during blasting.
Blo-Up is a three-component coupled model of rock blasting. A coupled modeling approach was chosen because no single numerical technique was found to adequately describe all the physical phenomena occurring during blasting. The three components are (i) a continuum geomechanics model for the early-time detonation and near-field crushing; (ii) a brittle discrete element model for stress wave propagation, fracturing and burden movement; and (iii) a gas product model for burden acceleration by gas expansion, fracture flow, and atmospheric venting.
