On modeling mixed hardening in computational plasticity [PDF]
Computers & Structures, 2004 Abstract We address herein the calculation of Prager’s hardening parameter in computational plasticity when mixed hardening is considered. We consider two approaches to evaluate the mixed hardening response; namely, based on splitting the plastic strains and based on splitting the plastic modulus.

Long-Term Evolution of Massive Black Hole Binaries. II. Binary Evolution in Low-Density Galaxies [PDF]
, 2005 We use direct-summation N-body integrations to follow the evolution of binary black holes at the centers of galaxy models with large, constant-density cores. Particle numbers as large as 400K are considered.

Plastic deformation of rough rolling contact: An experimental and numerical investigation [PDF]
, 2014 Quantifying the surface roughness evolution in contacts is a crucial step in the fatigue prediction process. Surfaces are initially conditioned by the running-in process and later altered by surface fatigue.

Collisional dynamics around binary black holes in galactic centers [PDF]
, 2001 We follow the sinking of two massive black holes in a spherical stellar system where the black holes become bound under the influence of dynamical friction. Once bound, the binary hardens by three-body encounters with surrounding stars.

Significant elastic anisotropy in Ti$_{1-x}$Al$_x$N alloys [PDF]
, 2002 Strong compositional-dependent elastic properties have been observed theoretically and experimentally in Ti$_{1-x}$Al$_x$ N alloys. The elastic constant, C$_{11}$, changes by more than 50% depending on the Al-content.

Beam element for large displacement analysis of elasto-plastic frames
Vietnam Journal of Mechanics, 2004 The present paper develops a non-linear beam element for analysis of elastoplastic frames under large displacements. The finite element formulations are derived by using the co-rotational approach and expression of the virtual work. The Gauss quadrature
