A micromechanical finite element model for linear and damage-coupled viscoelastic behaviour of asphalt mixture
This study presents a finite element (FE) micromechanical modelling approach for the simulation of linear and damage-coupled viscoelastic behaviour of asphalt mixture. Asphalt mixture is a composite material of graded aggregates bound with mastic (asphalt and fine aggregates). The microstructural model of asphalt mixture incorporates an equivalent lattice network structure whereby intergranular...
متن کاملFailure analysis of solder joints with a damage-coupled viscoplastic model
This paper presents failure analysis of solder joints with a damage-coupled viscoplastic model. A material model is developed to characterize the elasticity, plasticity, creep and damage of solder. A semiimplicit time-integration approach is adopted for the numerical implementation of the solder model. This solder model has been implemented into nite element codes developed at Sandia National L...
متن کاملa continuum/discontinuum micro plane damage model for concrete
analysis and prediction of structural response to static or dynamic loading requires prediction of concrete response tovariable load histories. the constitutive equations for the mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under loading/unloading/reloading was developed upon micro-plane framework. the proposed damage formulation has been built on t...
متن کاملA Viscoplastic Constitutive Model with Strain Rate Variables for Asphalt Mixtures’ Numerical Simulation
The study and development of recycling techniques for pavements is an increasing activity in engineering nowadays. This research line demands a more realistic characterization of the material properties with the aim of simulate the asphalt mixture’s response placed into a multilayered system over granular bases, under dynamic loads, considering also temperature variation or strenght reduction f...
متن کاملA Coupled Chemo-Elastoplastic- Damage Constitutive Model for Plain Concrete Subjected to High Temperature
A coupled elastoplastic-damage constitutive model taking into account chemo-induced elastoplastic-damage effects for the modeling of coupled chemothermo-hygro-mechanical behavior of concretes at high temperature is proposed in this article. A three-step operator split algorithm for the integration of the rate coupled constitutive equations is developed. Consistent tangent modulus matrices for c...
