We determine the innermost stable circular orbit (ISCO) of binary neutron stars (BNSs) by performing dynamical simulations in full general relativity. Evolving quasiequilibrium (QE) binaries that begin at different separations, we bracket the location of the ISCO by distinguishing stable circular orbits from unstable plunges. We study Gamma=2 polytropes of varying compactions in both corotation...

This paper provides an incremental layerwise finite element formulation for the viscoelastic analysis of multilayered pavements.  The constitutive behavior of asphalt concrete is represented by the Prony series. Layerwise finite element has been shown to provide an efficient and accurate tool for the numerical simulation of laminated structures. Most of the previous research on numerical simula...

Analysis of the stresses, displacements, and horizontal strains of the ground subsidence due to underground excavation in rocks can be accomplished by means of a hybridized higher order indirect boundary element/finite difference (BE/FD) formulation. A semi-infinite displacement discontinuity field is discretized (numerically) using the cubic displacement discontinuity elements (i.e. each highe...

Hygrothermal analysis of laminated composite plates has been done by using an efficient higher order shear deformation theory. The stress field derived from hygrothermal fields must be consistent with total strain field in this type of analysis. In the present formulation, the plate model has been implemented with a computationally efficient C0 finite element developed by using consistent strai...

The size dependent large displacement behavior of planar microbeams and microframes is studied in this paper using a corotational beam element. To account for the effect, modified couple stress theory (MCST) employed conjunction with Euler-Bernoulli deriving internal force vector tangent stiffness matrix Newton-Raphson based iterative procedure used combination arc-length method to solve nonlin...

Abstract The virtual element method has been developed over the last decade and applied to problems in solid mechanics. Different formulations have used regarding order of ansatz, stabilization a wide range including elastic inelastic materials fracturing processes. This paper is concerned with elements for higher gradient theories solids using possibility, inherent methods, formulating C 1 -co...
