Abstract
A new hypoplastic constitutive model with a modular structure is presented for granular soils. The modular structure allows the application of the constitutive model with very little material information under restriction of the soil effects to be reproduced. The more material information available, the better the stress–strain behaviour of the material can be represented. The basic model and six modules are presented that allow to model soil phenomena like barotropy, pyknotropy, load history, and small strain stiffness. Laboratory tests are simulated to show the performance of the constitutive model.
期刊介绍:
Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science.
These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations.
>> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa.
The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
