b) Encourage preparation of keynote lectures, introductory
lectures from TC103 on latest developments and new trends
on numerical methods with an emphasis on geomechanics.
In particular,
 We shall encourage all our members to take every chance
to promote the use of advanced computational methods
for geotechnical applications at international and regional
conferences and workshops
 Most executive members as well members recommended
from regional societies of TC103 are reputable experts in
their specific research areas within a broad field of
computational geomechanics. We are confident that many
of them will be invited from time to time by various inter-
national/regional conferences to deliver keynote lectures,
to teach for various workshop/summer schools and to
provide various technical inputs on practical problems.
These activities will be clearly documented in our news-
letter as well as annual report.
 Meanwhile, TC103 will also recommend appropriate
candidates from among our TC members to give these
speeches on occasions that we deem suitable, especially
those events organized by the overlapping organization as
will be listed in Objective 3.
 TC103 will also organize special issue publications in
some prestigious journals on thematic topics.
c) Develop various schemes to draw the active participation of
broad ISSMGE members. Typical examples of these in-
clude online survey of typical software packages used for
their research/work, challenging problems/difficulties they
have encountered or are facing in their daily work of
numerical analysis. Benchmark test competitions will also
be planned for all interested members to participate to test
the performance of their own packing/numerical schemes
on solving the same problem.
Objective 2:
TC103 will endeavour to provide full support for various inter-
national/regional conferences relevant to ISSMGE, to help on
organizing special sessions, calling for papers, recommending
keynote speakers, offering help on reviewing papers and on
seeking suitable sponsors. All members of TC103 will be
highly encouraged to contribute to these events and to present
their latest research developments on numerical modelling in
geomechanics. Specifically, we tentatively propose the follow-
ing thematic sessions be organized at the various conferences.
 A TC103 special session on "The Behavior of Material
Instabilities at Various Scales for Geomaterials" at the 9 th
IWBDG (2010) (Task leader: Prof. François Nicot)
 Two parallel sessions for the upcoming 14th ARC-SMGE
(2010)-Hong Kong: one on recent progress in computational
geomechanics and the other on the current practice and issues
of numerical methods for engineering. (Task leader: Dr.
Jonny Cheuk)
 A session (to be confirmed) for the 11th International Sympo-
sium on Landslides/2 nd North American Symposium on
Landslides, 2012, Canada (Task leader: Prof. Richard Wan/
Prof. François Nicot)
 A special session in 3 rd International Symposium on Com-
putational Geomechanics (ComGeo III), 2013 (Task leaders:
Prof François Nicot/Prof. Richard Wan)
 TC103 Mini-symposium on "Challenges and Opportunities in
Computational Geomechanics" for the 18 th ISSMGE Confer-
ence (2013)- France
TC103 will also organize special issues of thematic publica-
tions in such journals as Int. J. Analy. Numer. Meth. Geom. ,
Soils and Foundations and Computers and Geotechnics, as
well as the ISSMGE International Journal of Geoengineering
Case Histories if deemed as appropriate. Contribution to
these special issues will be based on invitation and/or in
connection with some of the above special conference ses-
sions.
Objective 3:
TC103 will actively seek every opportunity to interact with
geotechnical industry as well as other organization/society
relevant to computational geomechanics. Specifically:
a) We shall encourage all regional societies to recommend
experienced practicing engineering to join our technical
committee. We shall also encourage them to organize vari-
ous sessions with practice-oriented topics and discussion
sessions with academics involved. For example, in Hong
Kong area, we shall call for members from the Hong Kong
Institute of Engineers (HKIE) to join our TC, through
whom we shall regularly circulate conference/workshop/
seminar information to major consulting firms such as Ove
Arup, AECOM, Scott Wilson, governmental offices such
as GEO and contractors.
b) TC103 tentatively identities the following technical
committees of ISSMGE and other societies as potential
overlapping working bodies to interact with:
 TC105 Geomechanics from Micro to Macro of ISS-
MGE: the wide-spreading use of Discrete Element
Method for TC105 could offer invaluable information
for constitutive modelling of geomaterials at the contin-
uum level and help to shed light on the microscopic
mechanisms on various interesting phenomena such as
strain localization, liquefaction and progressive failure.
If possible, joint sessions can be proposed on suitable
occasions between TC103 and TC105.
 TC203 Earthquake Geotechnical Engineering and
Associated Problems of ISSMGE: The earth appears to
enter another seismic active period and our memory is
still fresh on the extreme disasters several recent major
earthquakes have caused. Computational intensive tools
have been developed to evaluate the occurrence prob-
ability potential consequence of earthquake at many
locations of the world. We shall work closely with our
colleagues in TC203 on the recently findings by them
and from our TC103 and seek chances to interact with
them on such occasions as regional and international
annual earthquake conferences.
 TC106 Unsaturated Soils of ISSMGE: The understand-
ing of unsaturated soil behaviour remains a difficult
topic. One active research area in unsaturated soil is to
develop suitable constitutive models to describe the soil
behaviour and to implement them in numerical codes
such as Finite Element Method for practical predictions.
As the latter falls precisely to our main themes and
