GeoHyTE

Journal paper on GeoHyTE

A journal article presenting GeoHyTE's beta version 1.3 was published by Algorithms. Besides presenting GeoHyTE's workflow and interfaces, the paper features a full-fledge validation of the methodology supporting GeoHyTE and assesses its performance as compared to a wide range of alternative time and frequency domain interpretation techniques for bender element tests ( spoiler: it works :) ). Moreover, the paper assesses the robustness of GeoHyTE's results to imperfect first guesses of the shear modulus and to coarse refinements of the finite element model.

As the authors put it, "We believe that this paper will enable GeoHyTE to become a mainstream signal interpretation technique for bender element sensors". Or at least we hope so... :)

The paper is published in Open Access so feel free to download and read it.

Description

GeoHyTE is a computational tool for the automatic identification of the small strain shear modulus of geomaterials from the output signal of bender element tests. It is based on the fixed-point model updating procedure reported here, which searches for the shear modulus that maximises the correlation between the output signals obtained experimentally and numerically.

GeoHyTE is highly insensitive to the starting point of the maximisation process and able to find the global maximum despite the presence of local extrema. Moreover, the convergence rate is very high. As opposed to most conventional interpretation techniques, the procedure implemented in GeoHyTE is objective (as it does not depend on the experience of the analyst) and physically-consistent (as it correlates signals of the same nature, obtained considering the physical features of the experiment).

GeoHyTE is user-friendly, featuring graphical user interfaces for all phases of the definition of the model, and outputs detailed descriptions of all fields at every iterations that can be used to visualise the solutions after (and even during) the execution.

A beta version of the software is distributed for testing to the scientific community and will be kept free for registered testers at all times. Interested colleagues are invited to register below.
