Viscoelasticity of Steel: Is it Right?

AI Thread Summary
Steel does not exhibit viscoelastic behavior at ordinary deformation rates, as it primarily demonstrates elastic properties without significant viscous characteristics. Under load, within its elastic limit, steel resists deformation and returns to its original shape after the load is removed. The stress in steel is directly related to the amount of deformation, rather than the rate of deformation. Therefore, it is incorrect to classify steel as viscoelastic in its elastic limit. Understanding these properties is crucial for applications involving steel in engineering and construction.

Viscoelasticity is a property of a material that exibits both viscous and elastic properties..

When under load,within elastic limit,steel offers resistance to deformation (viscous) and regains shape after removal of load..So is it right to say steel is VISCOELASTIC in elastic limit?

No. Steel is not viscoelastic at ordinary deformation rates and does not exhibit viscous type behavior. The stress is strictly a function of the deformation and not the rate of deformation.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
