Description of Time-Dependent Behavior of Quasi-Overconsolidated Osaka Pleistocene Clays Using Elasto-Viscoplastic Finite Element Analyses

Finite element formulation for modelling large deformations in elasto-viscoplastic polycrystals

Anisotropic, elasto-viscoplastic behaviour in polycrystalline materials is modelled using a new, updated Lagrangian formulation based on a three-field form of the Hu-Washizu variational principle to create a stable finite element method in the context of nearly incompressible behaviour. The meso-scale is characterized by a representative volume element, which contains grains governed by single ...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Simulation of long-term consolidation behavior of soft sensitive clay using an elasto-viscoplastic constitutive model

A Simplified Model Describing the Cyclic Behavior of Lightly Overconsolidated Clays in Simple Shear

The geological profile of submerged slopes of the continental shelf typically consists of normally to lightly overconsolidated clays with depths ranging from a few meters to a few hundred meters and very low slope angles. The stability of these slopes is often investigated with pseudo-static methods by reducing the dynamic loading to an equivalent inertial force. The simplifications are such th...

Evaluating the Soil Bearing Capacity Coefficients by Means of a Finite Element Program Based on Elasto - Plastic Mohr - Coulomb Behavior

A finite element program based on elastic –plastic model of Mohr-Coulomb criterion was used to evaluate the bearing capacity coefficients of soil under shallow strip flexible footing . The results were compared with others’ analytical results and it was found that the present study could offer quite consistent and rather precise values for the bearing capacity coefficients . &#10&#10The effect ...
