... safety seismic waves swelling Carbon steel is one of the principal structural materials being used extensively in piping systems in nuclear power plants. High temperature water or steam with high pressure flows at high velocities through these pipes. Erosion corrosion has caused wall thinning...

...Keisuke Minagawa; Satoshi Fujita Background: Since the Hanshin-Awaji Earthquake Disaster, the number of isolated structures has been greatly increased. The natural period of the isolation system is designed around 3 s , because the predominate period of observed seismic waves is usually 0.1 to 1 s...

... discs disc drives thermal shock seismic waves earthquakes computer equipment testing safety Historical electronic equipment design focused on survival of vertical shock and vibration levels. These are no longer the only criteria requiring a designer’s attention. Critical computer equipment...

... tests were conducted with the tank filled with water up to 2.4 m. The same shaking table as that of the slipping test was used. The shaking table was excited in single horizontal direction by an artificial seismic wave. The wave had a response spectrum of constant level for a relatively wide...

... February 2001 pressure vessels load distribution seismic waves plasticity yield stress A piping system under extreme loading conditions will experience plastic yielding, generally in limited areas. The yielding shall affect the dynamic response, both in terms of modal shapes...

... deformation are much higher than that due to wave propagation; The damage mechanism of pipelines in liquefaction areas, to a large extent, can be attributed to dynamic ground motion associated with partially liquefaction ground, rather than by static (or permanent) ground deformation; A seismic wave...
