TC101 - LABORATORY TESTING
LABORATORY STRESS STRAIN STRENGTH TESTING
OF GEOMATERIAL
Chair: Hervé di Benedetto
TERMS OF REFERENCE
 To promote co-operation and exchange of information
concerning research and developments in advanced
laboratory geotechnical testing, including apparatus,
techniques, data acquisition and interpretation.
 To encourage the application of advanced laboratory testing
in research; in integrated site characterization studies; and in
ground modelling.
 To explore how advanced testing can be used most
constructively in practical geotechnical engineering.
 To advance the above aims through collaboration with
specialists working in laboratory and field testing, sampling,
theoretical and numerical analysis, and in project
engineering and full scale observation. This will involve
close liaison with other ISSMGE TCs.
TC102 - IN-SITU TESTING
GROUND PROPERTY CHARACTERIZATION FROM IN-
SITU TESTS
Tests
Chair: Paul W. Mayne (USA)
TERMS OF REFERENCE
The TC proposes to a seven part mission with the following
objectives:
 To promote the utilization and improve the interpretation of
in-situ tests to enhance geotechnical site characterization,
including the determination of soil and rock properties, use
of borehole techniques, penetration tests, and geophysical
methods, and their variance.
 Maintain an international website and email network, as
well as hold several meetings, for interactive communication
among the TC102 members and geotechnical affiliates to
share ideas, information, and technical solutions. The
current TC102 website i
 Host the 4th international conference on site characterization
(ISC-4) in Recife, Brazil on 18-20 September 2012 to exchange
theoretical, practical, and applied research in the area of in-
situ testing and geotechnical site investigation:
 Maintain a set of international guidelines and standards for
in-situ testing methods for reference on procedures and
interpretation.
 Upgrade the social importance & relevance of our
geotechnical discipline within eyes of the public, private,
commercial, industrial, and military communities.
 TC102 members plan to continue their interactivities with
sister Technical Committee TC101 (Laboratory stress-strain-
testing behaviour).
 Prepare a list of important and relevant publications (best
reading materials) on the topics of in-situ testing and
geotechnical & geophysical site characterization as a
reference source and guide to members.
TC103 - NUMERICAL METHODS
NUMERICAL METHODS IN GEOMECHANICS
Chair: K.T. Chau
TERMS OF REFERENCE
TC103 Numerical Methods in Geomechanics is one of the
technical committees of International Society for Soil
Mechanics and Geotechnical Engineering (ISSMGE). TC103
aims to provide a forum for all interested members of ISSMGE
to explore the using of computational tools and developing of
advanced numerical methods to solve problems relevant to soil
mechanics and geotechnical engineering.
TC103 will deal with the following important technical issues:
 Constitutive modelling, calibrations of complex soil behaviour
and engineering problems such as instability, strain
localization and progressive failure of soil or rock structures;
 Advanced procedures for model validation and verification;
the development of accurate, robust and efficient numerical
methods for applications of varying needs;
 Modelling of coupled phenomena that are useful across
geotechnical engineering, rock engineering, petroleum
engineering, geothermal engineering;
 Assisting and promotion of exchange of knowledge between
the academia and practicing engineers.
 More specifically, TC103 will focus on the following thematic
topics relevant to soil mechanics and geotechnical engineering:
 Investigation on effective predictive approaches to better
understanding of coupled behaviour in geomaterials (such
as thermo-hydro-chemo-mechanical coupling), various
instabilities modes such as strain localization,
liquefaction, large deformation, underground water flow
and contamination, erosion and rapid flow in
geomaterials, thermo-related geomechanics;
 Development of advanced constitutive models to
characterize the complex behaviour of geomaterials,
including elasto-plasticity, visco-plasticity,
hypoplasticity, cyclic-plasticity, soil/rock degradation,
strain softening, rate-dependency and anisotropy;
 Development of advanced predictive tools based on new
numerical and analytical techniques, such as Finite
Element Method (FEM), Extended Finite Element
Method (X-FEM), Boundary Element Method (BEM),
Material Point Method (MPM), coupled Discrete
Element Method (DEM) and FEM, Moving Particle
Semi-implicit (MPS) method, Smoothed Particle
Hydrodynamics (SPH) method and Multiscale Modelling
(MM) method.
 Numerical implementation and calibration of advanced soil
models using laboratory and field testing data; determination
of model parameters using back analysis, and
homogenization of locally heterogeneous geomaterials.
 Critical evaluation of existing prediction approaches among
the empirical methods, laboratory testing, simple elastic and/
or elasto-plastic methods and limit analysis, and various
comprehensive numerical methods.
 Transfer of new knowledge to and training practicing
engineers of the ISSMGE to address important engineering
issues in dealing with natural hazards; promotion of
exchange of ideas and experience between academics and
practitioners.
 Over a term of four years from 2010 to 2013, TC103 will
strive to achieve the following objectives in line with the
