> ADVANCED NUMERICAL APPLICATIONS AND PLASTICITY IN GEOMECHANICS
>
> Udine June 26 - 30, 2000
>
> SCOPE
> =====
>
> The objective of the course is to present a state-of-the-art
> training on plasticity in geomechanics in relation to both theory and
> practice. The main objectives will be to describe: (a) advances and
> rationale for plasticity modelling in geomechanics, (b) the
> implementation of plasticity models in computer codes, and (c)
> numerical applications of plasticity models to engineering practice.
>
> The implementation emphasis will lie in numerical applications
> rather than classical limit analysis approaches.
>
> (a) The first part of the course will briefly review and justify
> the use of plasticity in geomechanics and then describe in greater
> detail advances regarding plastic constitutive equations for
> geomaterials. The emphasis of this section will be aimed at the
> theoretical background to the constitutive models available for
> analysing complex geomechanical boundary value problems. The
> following are some of the topics covered in this section.
>
> A review of elasto-plasticity and its relevance to geomaterials;
> failure criteria for geomaterials including Mohr-Coulomb,
> Drucker-Prager and more advanced smooth surfaces, and their
> interpretation in principal stress space; plastic potential surfaces;
> associated or non-associated plasticity;
>
> more advanced plasticity models (bounding surface, nested
> surfaces, generalised, classical); kinematic and double-hardening
> models;
>
> review of large deformations/rotations/strains in the context of
> elasto-plasticity; discussion of when these factors are import in
> modelling geomaterials;
>
> theory of coupled problems (e.g. Biot) in elasto-plasticity;
> strain softening and strain localisation models in fluid saturated
> media; mechanics of partially saturated media.
>
> (b) The second part of the course will describe implementation of
> the constitutive models in a computational environment usually
> involving the finite element method;
>
> implementation and numerical implementation of failure criteria in
> finite element programs, corners, stress redistribution algorithms
> (initial stress, viscoplasticity, local return algorithms); constant
> stiffness vs. tangent stiffness methods; elasto-plastic stress-strain
> matrices for finite element applications;
>
> implementation of strain softening models; numerical modeling of
> localisation with regularisation of shear banding;
>
> time-stepping algorithms for transient (first-order)
> elasto-plastic analyses; implementation of coupled algorithms (e.g.
> 8-node, 4-node overlays); issues relating to models that lead to very
> large systems of linear equations (e.g. Element-by-element
> algorithms); implications for computers with parallel architecture.
>
> (c) The third part of the course will describe some practical
> numerical applications of the methods with validation where possible
> against theoretical solutions and laboratory and measured
> performance. The emphasis will be on finite element numerical
> solutions as opposed to classical limit analysis approaches.
>
> All course participants will receive source code in the form of
> main programs and subroutine libraries (in Fortran) covering some of
> the applications described: analysis of slope stability in earth dams
> and embankments; earth pressures and bearing capacity, finite element
> modelling of highly heterogeneous elasto-plastic materials, soil
> improvement due to reinforcement and freezing, staged construction of
> embankments and excavations; embankment consolidation, tunneling.

be held in Tucson, AZ in January 2001. Information can be found at:
http://www.u.arizona.edu/~tkundu/10IACMAG
We would like to invite you to submit paper(s) and participate in the
conference. The due date for abstracts has been extended to 1 March
2000.
Sincerely, C.S.Desai
