In the conditions of general flat stress state created by uniformly distributed effects tension (compression) at infinity, mixed contact problem for an infinite isotropic plate with a circular hole, which contour reinforced closed elastic rib in presence symmetrical interfacial section boundary their connection and edges cut process deformation is smoothly contacted, considered. The components ...

A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...

The ac response of anisotropic high-T e superconductors in the mixed states is theoretically analyzed. The physical picture proposed by Geshkenbein, Vinokur and Fehrenbacher together with the theory of thermally assisted flux flow is generalized to include the material anisotropy. The results show that the transition in the real part and the peak in the imaginary part of magnetic ac permeabilit...

abstract   background: pseudoarthrosis of the tibia poses one of the most challenging treatment problems in all of orthopedics. the goal of the study was to assess the clinical outcome of intramedullary rod fixation in its treatment.   methods: the results of the management for nine patients with pseudoarthrosis of the tibia with im rod fixation were reviewed retrospectively between 1986 - 2006...

The Alekseevski-Tate equations have long been used to predict the penetration, penetration velocity, rod velocity, and rod erosion of long-rod projectiles or kinetic-energy penetrators [1]. These nonlinear equations were originally solved numerically, then by the exact analytical solution of Walters and Segletes [2, 3]. However, due to the nonlinear nature of the equations, the penetration was ...

Oscillation of an underground cylindrical rod located in infinite medium and equipped with a dynamic vibration damper is considered. The vibrations the structure occur from action harmonic forces along longitudinal axis bar. possibility decreasing amplitude using two-mass absorber series connection masses parameters absorbers were optimized for different values environmental parameters. It was ...

We investigate nonequilibrium underdamped Langevin dynamics of Brownian particles that interact through a harmonic potential with coupling constant K and are in thermal contact with two heat baths at different temperatures. The system is characterized by a net heat flow and an entropy production in the steady state. We compare the entropy production of the harmonic system with that of Brownian ...
