ABSTRACT

In this book, we first presented the original concepts of the Spatially Mobilized Plane (SMP) and the SMP criterion, which is an extension of the Mohr-Coulomb criterion to three-dimensional stress states. The Cam-clay models were then introduced briefly and the combination of the SMP criterion and the Cam-clay models were achieved using a transformed stress https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429177835/5c409190-48ac-46d3-9459-fbf01f5c866f/content/images/ch5_infig1.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>. Several elastoplastic models for geomaterials were then presented using the transformed stress https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429177835/5c409190-48ac-46d3-9459-fbf01f5c866f/content/images/ch5_infig1.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/> and the SMP criterion. These models are applicable to sands exhibiting positive and negative dilation, sands and clays with K0-consolidation anisotropy, and unsaturated soils. The elastoplastic constitutive tensors of these models for solving boundary value problems by means of the finite element method were also given. Table 5.1 shows a list of the models introduced in this book. This table also gives the mutual relationships between the Cam-clay model and our models.
