The dynamics of a cracked, distributed parameter rotor component is studied. The proposed model is a rotating Timoshenko shaft which is also flexible in extension and torsion. Two uniform fields are connected by a local, complex spring e... J Wauer - 《International Journal of Solids & Structur...

There is also a force now due to extension of the spring. If the spring remains straight it will act in the radial direction, but its effect is dependent on whether the spring is stretched or compressed. Figure 46.18 illustrates the forces acting on the mass and their resolution into radial...
Since wave diffraction is ignored, the Morison equation is valid only for slender objects, i.e. if the extension along the wave direction (in case of a vertical cylinder: the diameter D) is significantly smaller than the wave length λ: (5.8)Dλ<0.05 5.5.2 Potential flow approach An obje...
For example, you see the analysis in a minimal surface equation, but then you also realize it has connections with other geometric questions that are not just analysis. I am definitely very attracted to the idea that there are a lot of different facets in mathematics and seeing the ...
To cure this unphysical behaviour one clearly needs to use a non-linear spring force which gives a finite limit to the extension. Incorporating this modification into the constitutive equation enables the numerical solution of (some) flow problems to proceed to large Deborah numbers. Care is of ...

where the climate is dry and soils have a high amount of carbonate that makes strong and large soil aggregates, provides poor results for predicting theK-factor. This is in agreement with the reports by Vaezi et al.,19Hassan and Agha,18and Shabani et al.13Among the PTFs, Vaezi et al...
