Triaxial Test with Hardening Soil Material Model
In this example, a triaxial test is simulated using the Hardening Soil material model. The test consists of two stages; an initial isotropic compression followed by axial compression. A hyperbolic stress-strain relation is recovered. It is also verified that the asymptotic value of the ... Per saperne di più
Block Verification
This model shows how to set up a uniaxial compression test on a prestressed soil sample. Due to uniaxial compression and simple initial stress values, it is possible to determine the vertical yield stress analytically. The soil sample is modeled with soil plasticity and the Mohr–Coulomb ... Per saperne di più
Flexible and Smooth Strip Footing on a Stratum of Clay
A common verification problem for geotechnical problems is a shallow stratum layer of clay. In this example a vertical load is applied on the clay strata and the static response and the collapse load are studied. The clay is modeled as an elastic-perfectly plastic material and the ...

Failure of a Concrete Beam Using Coupled Damage–Plasticity
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Per saperne di più
Triaxial Test
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... Per saperne di più
Triaxial and Oedometer Test with Modified Cam-Clay Material Model
In this example, triaxial and oedometer tests are simulated using the Modified Cam-Clay material model. A nonlinear stress-strain relation is recovered with the constant Poisson's ratio formulation. The hardening and softening behavior is recovered for normally consolidated and highly ... Per saperne di più

Isotropic Compression with Modified Cam-Clay Material Model
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Per saperne di più
Mechanical Modeling of Bentonite Clay
In this example, the Extended Barcelona Basic Model (BBMx) is used to model oedometer, uniaxial swelling, triaxial, and constrained swelling tests on bentonite clays in order to recover the hydromechanical characteristics of the soil samples. There is a good qualitative agreement ... Per saperne di più
Isotropic Compression Test for Structured Clays
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Per saperne di più
