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:

a) Constitutive modeling, calibrations of complex soil behavior and engineering problems such as instability, strain localization and progressive failure of soil or rock structures;

b) Advanced procedures for model validation and verification;

c) The development of accurate, robust and efficient numerical methods for applications of varying needs;

d) Modeling of coupled phenomena that are useful across geotechnical engineering, rock engineering, petroleum engineering, geothermal engineering;

e) Assisting and promotion of exchange of knowledge between the academia and practicing engineers.

TC103 will focus on the following thematic topics relevant to soil mechanics and geotechnical engineering:

a) Investigation on effective predictive approaches to better understanding of coupled behavior 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;

b) Development of advanced constitutive models to characterize the complex behavior of geomaterials, including elasto-plasticity, visco-plasticity, hypoplasticity, cyclic-plasticity, soil/rock degradation, strain softening, rate-dependency and anisotropy;

c) 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 Modeling (MM) method.

d) 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.

e) 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.

f) 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.

TC103 will promote the dissemination of knowledge and practice to the member of ISSMGE on employing advanced numerical methods to facilitate deeper understanding of fundamental behavior of geomaterials and to help solving difficult problems that are of practical importance. TC103 members will be encouraged to

a) actively engage in organizing/co-organizing workshops/symposiums/conferences to facilitate the exchange of ideas and advances in computational geomechanics among academics and practitioners.

b) deliver keynote lectures and introductory lectures to the public on latest developments and new trends on numerical methods with an emphasis on geomechanics.

c) develop various schemes to draw the active participation of broad ISSMGE members. Typical examples of these include 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.

d) the Scott Sloan honour lecture will be delivered (at least) every four years during the Numerical Methods in Geotechnical Engineering (NUMGE) Conference or a similar event in which TC103 is strongly involved. 

TC103 will actively seek opportunities to interact with geotechnical industry as well as other organization/society relevant to computational geomechanics. We shall encourage all regional societies to recommend experienced practicing engineering to join our technical committee. We shall also encourage them to organize various sessions with practice-oriented topics and discussion sessions with academics involved. TC103 will also actively seek collaborative opportunities to other ISSMGE technical committees as well as other professional societies to promote the advance of numerical methods in geomechanics and geotechnical engineering.

In the framework of the Virtual Time Capsule Project, TC103 encouraged a reflection about

1. The past:
what are the key developments in numerical methods?

2. The present:
what is the current use of numerical methods?

3. The future:
what will be the future? How can we improve it?

The material prepared by TC103 is accessible here. You will find a presentation on the development of numerical methods along time, summarized in the academic roadmap, and a survey on present and future needs of numerical methods.
