The R&D activities in JAERI cover the development of superconducting proton linear accelerator, the LBE technology, the irradiation damages of materials, and the reactor physics of the subcritical reactor.
The failure of a single-layer reticulated dome under a strong seismic load is due to the failure in dynamic strength resulting from the excessive damage of material.
In this paper the modified Duffing equations are applied to detect the SHG signals relating to the fatigue damage of material.
After that age, residual stress in plain mortar goes up quickly and induces the damage of material, which implies the higher possibility to crack with the past of age.
Multi-scale damage of material has been a concern in recent times owing to emphases of making devices in sizes smaller and smaller until the bulk average of the macroscopic material properties are no longer adequate while particle physics still lacks the expediency of engineering applications.
In the second part, the influence of spinning and weaving processes on the damage of textile materials is presented.
"In terms of material damage, the four strongest buildings on the island of St .Martin have been destroyed," Collomb told reporters, suggesting that weaker structures on the island had likely been leveled by Irma.
Understanding the behavior of deforming materials is essential for better designing innovative materials and identifying damage of materials in service.
A comprehensive approach to the continuous damage of materials is formulated within the framework of thermodynamic reasoning.
Fatigue, the damaging of materials under cyclic loading, is the main phenomenon leading to failure in e.g. automobile and aerospace components.
However, the surface damage of materials during nanowear process was not only depended on contact pressure P c, but also on the number of nanowear cycles N, displacement amplitude D, tribochemistry and other frictional factors [19, 20, 23, 30].
