This article presents a 3-D multiplicative finite strain model for cold drawing (necking) in engineering thermoplastics. Amorphous as well as semi-crystalline polymers are considered. The notion of intermediate (local) stress-free configuration, that is associated with the multiplicative decomposition of the deformation gradient, is shown to provide an appropriate framework for the modeling and...

Inelastic hadron diffraction refers to quasi-elastic transitions in which the colliding particles conserve their dominant quantum numbers. High energy of collision facilitates to satisfy the condition of coherence thus assuring that interaction does not change the character of the particles. High energy elastic scattering of hadrons is thus generally built of: i) elastic diffraction which resul...

The paper proposes an adaptive fiber section discretization scheme for inelastic frame elements. uses cubature rules the efficient and accurate evaluation of response over elastic portion section. As strains arise penetrate into from edges, converts area under to a regular discretization. This approach offers considerable advantages computational efficiency large structural models with elements...

Measurements of elastic and inelastic cotunneling currents are presented on a two-terminal Aharonov-Bohm interferometer with a Coulomb-blockaded quantum dot embedded in each arm. Coherent current contributions, even in a magnetic field, are found in the nonlinear regime of inelastic cotunneling at a finite-bias voltage. The phase of the Aharonov-Bohm oscillations in the current exhibits phase j...

We investigate driven wave turbulence in non-Abelian plasmas, in the framework of kinetic theory where both elastic and inelastic processes are considered in the small angle approximation. The gluon spectrum, that forms in the presence of a steady source, is shown to be controlled by nonlocal interactions in momentum space, in contrast to the universal Kolmogorov-Zakharov spectra. Assuming stro...

The knee bracing steel frame (KBF) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. Rather than the beam-column joint, one end of the diagonal brace in KBF is attached to the knee element. Indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...

To evaluate the earth seismic response due to earthquake effects, ground response analyses are used to predict ground surface motions for development of design response spectra, to compute dynamic stresses and strains for evaluation of liquefaction hazards, and to determine the earthquake induced forces that can lead to instability of earth and earth-retaining structures. Most of the analytical...

The analytical methods available to the design engineer today are either dynamic time history analyses, or monotonic static nonlinear analyses, or equivalent static analyses with simulated inelastic influences. This paper suggests in addition to the inelastic time history analyses, some simplified analyses techniques based on equating the seismic demand expressed in terms of response spectra wi...

Constitutive Modeling of Creep of Single Crystal Superalloys. (August 2005) Sharat Chand Prasad, B.Tech., Indian Institute of Technology, Kanpur; M.S., Texas A&M University Chair of Advisory Committee: Dr. K. R. Rajagopal In this work, a constitutive theory is developed, within the context of continuum mechanics, to describe the creep deformation of single crystal superalloys. The constitutive ...

Fig. 1. Schematic picture of inelastic (a) and elastic (b) vector meson leptoproduction Vector mesons can be produced in two different ways in lepton proton scattering, in so-called inelastic processes, where the proton breaks, or elastic (exclusive) processes, where the incoming proton stays intact. The different production mechanisms are shown schematically in Fig. 1. They suggest that the cr...
