This work deals with the transient hydroelastic analysis of a sandwich beam which represents a boat hull. The beam is subjected to slamming pressure while it enters into water with constant vertically downward velocity. A coupled hydroelastic finite element model is developed using higher order shear and normal deformation theories for the faces and the core of the beam and the velocity potenti...

A 14 year old girl presented with severe tricuspid regurgitation after she was diagnosed with "transient tricuspid regurgitation of the newborn". In the neonatal period she had presented with severe tricuspid regurgitation without an obvious underlying anatomical cause. This spontaneously regressed during the first months of life. She was dismissed from follow up at the age of 5 years after com...

The present article deals with transient thermal stress calculation on a safety horizontal shell and tube condenser. This condenser is used in power plant for cooling of hot steam diverted from the turbine case its emergency shutdown. standard was provided according to EN 13445 steady regime. As consistent this calculation, an expansion joint must be shell. main aim describe detailed temperatur...

In the context of continental extension, transient compressional episodes (stress inversion) and phases uplift (depth are commonly recorded with no corresponding change in plate motion. Changes gravitational potential energy during rifting process have been invoked as a possible source stresses, but their magnitude, timing, relationship depth inversions remain unclear. Using high-resolution two...

Synopsis The stress vs strain curves in dense colloidal dispersions under start up shear flow are investigated combining experiments on model core shell microgels, computer simulations of hard disk mixtures, and mode coupling theory. In dense fluid and glassy states, the transient stresses exhibit first a linear increase with the accumulated strain, then a maximum (stress overshoot) for strain ...

BACKGROUND Reoxygenation of ischemic tissues is a major factor that determines the severity of cardiovascular diseases. This paper describes the consequences of anoxia/reoxygenation (A/R) stresses on Drosophila, a useful, anoxia tolerant, model organism. METHODOLOGY/PRINCIPAL FINDINGS Newly emerged adult male flies were exposed to anoxic conditions (<1% O2) for 1 to 6 hours, reoxygenated and ...

The resilience of microbial functions like carbon (C) and nitrogen (N) cycling to stress is likely heavily dependent on pH. Past research, however, has been limited laboratory manipulations or a pH gradient resulting from differences in soil mineralogy. In this study, soils were collected >50-year field trial where plots have maintained at 4.9, 6 7.1. We selected copper (Cu) heat represent pers...

This study is focused on the performance evaluation of flash-butt-welded rail joints concerning their mechanical strength and fatigue life. Residual stresses created in heat-affected zone were measured effects welding process notch sensitivity behavior weld region experimentally assessed. Aiming at clarifying physical phenomenon behind flash-butt welding, nonlinear transient thermomechanical fi...

Nonlinear extended MHD simulations demonstrating seeding of neoclassical tearing modes (NTMs) via MHD-transient-induced multimode interactions are presented. Simulations NTMs enabled by two recent NIMROD code developments: the implementation heuristic stresses and application transient magnetic perturbations (MPs) at boundary. driven unstable inherently pressure kinetic bootstrap current, which...
