In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship. This basic feature of the framework has the advantage that yield criteria, flow and hardening rules are formulated on planes rather than in three-dim...

Johnson-Cook constitutive equation is one of the most famous constitutive equations that have ever been developed to model the hot deformation flow curves of different materials. This equation is a predefined model in the traditional finite element codes to describe the material behavior in applications such as simulating the manufacturing processes. In this work, two different genetic algorith...

In Geo-engineering design, Geotech-engineers usually adopt ‘Mohr-Coulomb model (M-C)’ to substitute most soil material, this is considered as linear elastic and perfectly plastic model, despite, in the coastal engineering, sand-clay mixed with water, cement, fine aggregate or similar materials are common interface medium among pile bodies, frictions from them have strong affection on piles sett...

nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. in some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. theref...

Understanding mechanical interactions at the root-soil interface is essential to predict erosion of vegetated slopes. Recently, shear strength vegetatedil under changing hydraulic conditions has been measured and modeled; however, interfaces have not investigated conditions. This paper proposes (1) a novel pullout apparatus measure suction, (2) Mohr-Coulomb-Vilar (MCV) model interfaces, (3) num...
