Modelling of Soil Behaviour with Hypoplasticity
Author: David Mašín
Publisher: Springer
ISBN: 3030039765
Category : Science
Languages : en
Pages : 199
Book Description
This book explains the hypoplastic modelling framework. It is divided into two parts, the first of which is devoted to principles of hypoplasticity. First, the basic features of soil’s mechanical behaviour are introduced, namely non-linearity and asymptotic properties. These features are then incorporated into simple one-dimensional hypoplastic equations for compression and shear. Subsequently, a hypoplastic equivalent of the Modified Cam-Clay model is developed in 2D space using stress and strain invariants to demonstrate key similarities and differences between elasto-plastic and hypoplastic formulations. Lastly, the mathematical structure of hypoplastic models is explained by tracing their historical development, from the early trial-and-error models to more recent approaches. In turn, Part II introduces specific hypoplastic models for soils. First, two reference models for sand and clay are defined. After summarising their mathematical formulations, calibration procedures are described and discussed. Subsequently, more advanced modelling approaches are covered: the intergranular strain concept incorporating the effects of small strain stiffness and cyclic loading, viscohypoplasticity for predicting rate effects, soil structure to represent structured and bonded materials and soil anisotropy. The book concludes with a description of partial saturation and thermal effects: topics that are increasingly important to the disciplines of energy and environmental geotechnics. Selecting a constitutive model and its parameters is often the most important and yet challenging part of any numerical analysis in geotechnical engineering. Hypoplasticity involves a specific class of soil constitutive models, which are described in detail here. The book offers an essential resource, both for model users who need a more advanced model for their geotechnical calculations and are mainly interested in parameter calibration procedures, and for model developers who are seeking a comprehensive understanding of the mathematical structure of hypoplasticity.

Publisher: Springer Science & Business Media
ISBN: 3642570186
Category : Science
Languages : en
Pages : 558
Book Description
In view of its extreme complexity the mathematical description of the mechanical behaviour of granular materials is an extremely difficult task. Today many different models compete with each other. However, the complexity of the models hinders their comparison, and the potential users are confused and, often, disencouraged. This book is expected to serve as a milestone in the present situation, to evaluate the present methodes, to clear up the situation, to focus and encourage for further research activities.

Hypoplastic Left Heart Syndrome
Author: Jack Rychik
Publisher: Springer Science & Business Media
ISBN: 1461502535
Category : Medical
Languages : en
Pages : 430
Book Description
Despite approximately 50 years of progress in the management of com plex congenital heart disease, hypoplastic left heart syndrome (HLHS) has been one of the last cardiac malformations to yield to effective surgical treat ment. The surgical therapies for hypoplastic left heart syndrome have evolved by two quite disparate routes. One approach has been the staged reconstruc tion operations utilizing an initial operation pioneered by many but developed by Dr. William Norwood and subsequently modified by many other investigators. The first stage reconstruction operation has been refined and standardized such that the majority of infants now proceed to second and third stage reconstruc tive operations culminating in a Pontan Kreutzer single ventricle physiology. An alternative surgical approach has been the development of neonatal and infant heart transplantation for HLHS. This approach also has had a signifi cant impact on the treatment of HLHS and other cardiac malformations and has been associated with good intermediate term results. Both of the thera peutic approaches devised for treatment of hypoplastic left heart syndrome have been effective and the outcomes are continuing to improve with each.

Constitutive Modeling of Geomaterials
Author: Qiang Yang
Publisher: Springer Science & Business Media
ISBN: 3642328148
Category : Science
Languages : en
Pages : 779
Book Description
The Second International Symposium on Constitutive Modeling of Geomaterials: Advances and New Applications (IS-Model 2012), is to be held in Beijing, China, during October 15-16, 2012. The symposium is organized by Tsinghua University, the International Association for Computer Methods and Advances in Geomechanics (IACMAG), the Committee of Numerical and Physical Modeling of Rock Mass, Chinese Society for Rock Mechanics and Engineering, and the Committee of Constitutive Relations and Strength Theory, China Institution of Soil Mechanics and Geotechnical Engineering, China Civil Engineering Society. This Symposium follows the first successful International Workshop on Constitutive Modeling held in Hong Kong, which was organized by Prof. JH Yin in 2007. Constitutive modeling of geomaterials has been an active research area for a long period of time. Different approaches have been used in the development of various constitutive models. A number of models have been implemented in the numerical analyses of geotechnical structures. The objective of the symposium is to provide a forum for researchers and engineers working or interested in the area of constitutive modeling to meet together and share new ideas, achievements and experiences through presentations and discussions. Emphasis is placed on recent advances of constitutive modeling and its applications in both theoretic and experimental aspects. Six famous scholars have been invited for the plenary speeches of the symposiums. Some prominent scholars have been invited to organize four specialized workshops on hot topics, including “Time-dependent stress-strain behavior of geomaterials”, “Constitutive modeling within critical state soil mechanics”, “Multiscale and multiphysics in geomaterials”, and “Damage to failure in rock structures”. A total of 49 papers are included in the above topics. In addition, 51 papers are grouped under three topics covering “Behaviour of geomaterials”, “Constitutive model”, and “Applications”. The editors expect that the book can be helpful as a reference to all those in the field of constitutive modeling of geomaterials.
