Finite Element Simulations of an Elasto-Viscoplastic Model for Clay

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

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 ...

On Finite Element Implementation for Cam Clay Model

Cam clay models are one of the popularly used soil plasticity models. Finite element implementation of these models requires integration of constitutive relations and load stepping scheme. There have been considerable advances in the integration of constitutive relations. These methods can be grouped as explicit and implicit methods. The superiority of one over the other lies in the context of ...

An elasto-viscoplastic interface model for investigating the constitutive behavior of nacre

In order to better understand the strengthening mechanism observed in nacre, we have developed an interface computational model to simulate the behavior of the organic present at the interface between aragonite tablets. In the model, the single polymer-chain behavior is characterized by the worm-like-chain (WLC) model, which is in turn incorporated into the eight-chain cell model developed by A...

an application of equilibrium model for crude oil tanker ships insurance futures in iran

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
