The main arch rib is composited of one steel pipe with diameter 110mm and wall thickness 2mm, and two steel pipes with diameter 75mm and wall thickness 1.5mm.
The natural frequency, damping ratio and mode shape is related to the structural type, mass distribution, stiffness, material property and boundary conditions [8-10].

In this sense, one of the most important points in geochemical prospecting is the selection of threshold values to separate the regional background (understood as the mean content of each element considered in a geological material) and the positive geochemical anomalies, i.e
In this sense, one of the most important points in geochemical prospecting is the selection of threshold values to separate the regional background (understood as the mean content of each element considered in a geological material) and the positive geochemical anomalies, i.e. unusually high contents of those elements in that particular geological context.

A wide range of abrasive materials is used in the CMP processes.
Note, that to estimate the crack opening one can neglect by a difference of deformation properties of contacting materials loading to some tangential forces.
