Mr. Wang is a senior geomechanics engineer with experience in mining engineering and geotechnical engineering. His research involves numerical modeling and simulation, and has involved projects related to sheet-pile walls with retained slope, mine-void detection using geophysical methods and stability of underground mines.
FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Ms. Zetterlund is Itasca’s Training and Education Coordinator. Judy coordinates Itasca Consulting Group trainings; introductory trainings each spring, more focused trainings in the fall, and customized trainings upon request.
Masonry is one of the oldest methods of construction, but has lost nothing of its attractiveness and use in modern times. The behavior of this heterogeneous and anisotropic material is determined by the interaction of stone (brick, quarry stone, natural stone, etc.) and joints (open, mortar, glued, etc.). The behavior and performance of masonry structures under load is characterized by complex deformation and failure mechanisms involving different forms of stone and joint failure and interactions.
Modern numerical simulations can provide reliable assessments of the performance as well as potential failure processes (i.e., collapse) of masonry structures. Due to the nature of these structures—with the possibility of discrete dislocations and rotations—the discrete element method (DEM) is well suited for modeling them. The software UDEC and 3DEC
developed by Itasca offer unique simulation possibilities for historical buildings (bridges, churches, medieval buildings, walls, etc.), as well as for modern masonry structures. Due to the explicit method of calculation, dynamic events (e.g., earthquake vibrations, or shocks) can be well captured. Successful consulting projects and R&D projects have been carried out for both historic buildings and modern construction.
