A cyclic elasto-plastic constitutive model based on a non-linear kinematic hardening rule for sand is proposed. Three points are incorporated into the model: new flow rule, cumulative strain-dependent characteristic of plastic shear modulus and fading memory initial anisotropy model. In order to verify its effectiveness, proposed was evaluated by means results series hollow-cylinder torsional tests with without an stress after isotropic anisotropic consolidation. The liquefaction strength...
This is a reconnaissance report on the damage to buildings, bridges, and other structures caused by 2009 L'Aquila, Italy earthquake. The authors conducted site investigation during period of April 18–21, 2009. A detailed discussion facilities, as well possible mechanisms, presented. Geotechnical ground motions are also
A numerical method is developed for the prediction of large deformations associated with a geomaterial flow during occurrences such geo-disasters as landslides and slope failures. The modeled viscous fluid, where Bingham type constitutive model proposed based on Coulomb's failure criterion viscosity derived from cohesion friction angle. Numerical experiments 2D gravitational column show that performs well. For solving Navier-Stokes's equations, Constrained Interpolated Profile (CIP) scheme...
Abstarct Here we apply a two-phase flow model to simulate snow avalanche motion. Flowing is modeled as Bingham fluid. Small-scale laboratory experiments were conducted using rotating viscometer validate the constitutive model. Experimental scale test-runs also performed, and run-out distances impact pressures obtained in tests reproduced Comparisons revealed that simulated results strongly dependent on basal friction angle calculation mesh size. Although method quite well, aspects of surface...
In the paper, based on a modified elastoplastic model with Matsuoka-Nakai failure criterion, two-dimensional (2D) and three-dimensional (3D) soil-water coupled finite element analyses are conducted to investigate large-scale in soft-rock slope due heavy rain. Since of was typical event, it is necessary estimate accuracy 2D analysis that can be easily commonly used geotechnical engineering. The characteristics failure, such as development shear strain, deformation ground, propagation band...
