This is a practical paper which consists of investigating fracture behavior in asphalt concrete using an intrinsic cohesive zone model CZM . The separation and traction response along the cohesiveâ€¦ (More)

The computational bottleneck of topology optimization is the solution of a large number of linear systems arising in the finite element analysis. We propose fast iterative solvers for largeâ€¦ (More)

This paper is directed towards :nite element computation of fracture parameters in functionally graded material (FGM) assemblages of arbitrary geometry with stationary cracks. Graded :nite elementsâ€¦ (More)

Large-scale simulation of separation phenomena in solids such as fracture, branching, and fragmentation requires a scalable data structure representation of the evolving model. Modeling of suchâ€¦ (More)

Domains containing an `internal boundary', such as a bi-material interface, arise in many applications, e.g. composite materials and geophysical simulations. This paper presents a symmetric Galerkinâ€¦ (More)

We explore the recently-proposed Virtual Element Method (VEM) for the numerical solution of boundary value problems on arbitrary polyhedral meshes. More specifically, we focus on the linearâ€¦ (More)

This paper presents a â€˜â€˜simpleâ€™â€™ boundary element method for transient heat conduction in functionally graded materials, which leads to a boundary-only formulation without any domain discretization.â€¦ (More)

The concept of functionally graded materials (FGMs) is closely related to the concept of topology optimization, which consists in a design method that seeks a continuum optimum material distributionâ€¦ (More)

Anisotropic strain gradient elasticity theory is applied to the solution of a mode III cr in a functionally graded material. The theory possesses two material characte lengths,, and ,8, whichâ€¦ (More)
