Dr. Aglawe is a mining engineer with experience in rock mechanics (hard and soft rock) and in application of advanced numerical modeling for mining and civil projects. He has been involved in the development of models for tunnels, caverns and dams in hydroelectric projects.
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 Fifth International Itasca Symposium will be held at the University of Vienna (Austria). The Symposium will features the application of Itasca software for solving engineering and scientific challenges in geomechanics, hydrogeology, microseismicity, and more.
Mr. Ukey provides administrative support to our office and is involved in software sales. He is the first contact for software sales.
The Universal Distinct Element Code (UDEC) is a two-dimensional
numerical program that simulates the quasi-static or dynamic response to
loading of media containing multiple intersecting joint structures.
The discontinuous medium is represented as an assemblage of discrete
blocks while the discontinuities are treated as boundary conditions
between blocks. Large displacements along discontinuities and rotations
of blocks can occur. UDEC utilizes an explicit solution scheme that can
model complex, nonlinear behaviors.
Models may contain a mix of rigid or deformable blocks. Deformable
blocks are defined by a continuum mesh of finite-difference zones, with
each zone behaving according to a prescribed linear or nonlinear
stress-strain law. The relative motion of the discontinuities is also
governed by linear or nonlinear force-displacement relations for
movement in both the normal and shear directions. Joint models and
properties can be assigned separately to individual, or sets of,
Because UDEC is not limited to a particular type of problem or initial
condition, it may be applied to a wide variety of physical behaviors
or any case where an understanding of the two-dimensional response of
such structures is needed. UDEC is capable of simulating a wide range of engineering and scientific analyzes including: stability analysis of jointed rock slopes or underground excavations; fluid or gas flow through jointed rock; stability of masonry structures, dams, and foundations; blasting, earthquakes, and microseismicity; among many more applications.
Optional features are specialized modules that can be added to UDEC at an additional cost for additional simulation tools.
Barton-Bandis Joint Analysis: The Barton-Bandis
joint model utilizes a series of empirical relations for joint normal
behavior and joint shear behavior based on the effects of surface
roughness on discontinuity deformation and strength as described by Barton (1982) and Bandis et al. (1985).Creep Material Analysis: The creep option can be used to simulate the behavior of materials that time-dependent material behavior.
User-Defined Models (UDM): With this option, users may create their own contact or zone constitutive model for use in UDEC using C++ scripting.
Thermal Analysis: The
thermal model simulates the transient flux of heat in materials and the
subsequent development of thermally induced stresses. The heat flux is
modeled by either isotropic or anisotropic conduction. Heat sources can
be added and can be made to decay exponentially with time.
