Modelling of the fatigue cracking resistance of grid reinforced asphalt concrete by coupling fast BEM and FEM
نویسندگان
چکیده
We present a computational modelling approach aimed at investigating the effect of fibre grid reinforcement on crack opening displacement and fatigue propagation. Grid reinforcements are modelled using elastic membrane finite elements, while cracked concrete is treated symmetric boundary element method (BEM), which in particular allows easy geometrical meshing cracks. The BEM accelerated by fast multipole method, allowing handling potentially large models entailed three-dimensional configurations hosting multiple Fatigue growth Paris law. proposed first verified reinforced beam, then applied to configuration featuring grid-reinforced asphalt pavement.

Coupling of Natural BEM and Composite Grid FEM
The coupling of boundary elements and finite elements is of great importance for the numerical treatment of boundary value problems posed on unbounded domains. It permits us to combine the advantages of boundary elements for treating domains extended to infinity with those of finite elements in treating the complicated bounded domains. The standard procedure of coupling the boundary element and...

This paper is concerned with the coupling of non-conform nite element and boundary element methods in continuation of Part I (C. Carstensen, S.A.

In this paper, we establish sharp a posteriori e...

BEM-FEM coupling is desirable for three-dimensional problems involving specific features such as (i) large or unbounded media with linear constitutive properties, (ii) cracks, (iii) critical parts of complex geometry requiring accurate stress analyses. However, for cases with a BEM discretization involving a large number NBEM of degrees of freedom, setting up the BEM contribution to the coupled...
متن کاملSubstrate Resistance Modeling by Combination of BEM and FEM Methodologies
In present-day IC’s, substrate noise can have a significant impact on performance. Thus, modeling the noise-propagation characteristics of the substrate is becoming ever more important. Two ways of obtaining such a model are the Finite Element Method (FEM) and the Boundary Element Method (BEM). The FEM makes a full 3D discretization of the entire substrate and is very accurate and flexible, but...
