Uniqueness, second order work and bifurcation in hypoplasticity

Comparison between Theoretical and Experimental Behavior of Shallow Foundation in Cohesive Soil

“…The constitutive models, in general, that perform in trade software are so easy (Mohr-Coulomb model (MC), Hardening soil model (HS), Hardening soil model with small-strain stiffness (HSsmall)). Despite the complexity of the component of the soil and the new constitutive relationship that was recently developed (Carve (1990), Champion (2000), Dayflies and Manzari (2004), Muir Wood (2004), as recently suggested by Muir Wood (2004)) so as to permit geotechnical engineers to solve experimental issues considering more reasonable soil behavior, more effort should be made to implement new constitutive soil models in numerical trade codes [5][6][7][8]. Moreover, the research goal is to explore the best matching of the finite element model with the experimental load-displacement curve using different finite element models and to study the effect of some parameters on the load settlement relation curve like the size of footing, modulus of elasticity, and internal friction angle.…”
