Numerical Analyses In Geotechnical Engineering And Computer Applications


  REF: GE535  DATES: 16 - 20 Jul 2018  (One Week)  VENUE: Malaysia (Kuala Lumpur)-Grand Millenium Hotel

Overview:

Over the past ten years the use of sophisticated numerical techniques to analyse geotechnical problems has grown significantly. Such methods are now being used routinely in design, with many software packages available for performing the analysis. Due to the nonlinear nature of soil behaviour, the theory used by these programs is non-unique and therefore there are major differences in the way programs function. This can result in much confusion to the user.

objective:

the objective to provide insight into the use of advanced methods of analysis in geotechnical practice, in particular the finite element and, more recently, discrete element methods. By means of practical examples both the advantages, and restrictions and pitfalls, of these methods are presented and discussed. The lectures cover both static and dynamic analysis of saturated and unsaturated soils.

Who Should attend:

The course should be of interest to a wide range of practising civil engineers and numerical analysts at different stages in their careers.
