One of the mechanism that affect corrosion is known in the literature as Stress Corrosion Cracking (SCC). The idea is that tensile stressed regions are prone to crack development. Crack development essentially maximizes the area that corrosion can develop. Since corrosion, degrades the properties of the material, this accelerates further the crack ...

In the real world ,I don't believe I have seen CORROSION at STRESSED areas. Corrosion may be accelerated at STRAINED areas; the strains introduce energy to the microstructure which may promote corrosion. Cracking is another story - which you did not ask about . Hydrogen cracking of high strength steels is likely the most common case . It can often occur with ...

The quote (from Wikipedia) below answers your question (in general). Otherwise, you shall provide specific example to obtain meaningful response. "The strain rate at some point within the material measures the rate at which the distances of adjacent parcels of the material change with time in the neighborhood of that point. It comprises both the rate at ...

I'm not an expert, but the disk in a disk brake system needs to absorb enourmous amounts of heat to dissipate the energy of motion. It then needs to transfer that heat to the air. Polymers generally are poor heat conductors and have relatively low heat capacity. Add to this lower strength and you have a poor choice for disk material. As Jim Clark mentions in ...

Well mass and high-temperature behavior are really the key benefits with carbon/ceramic brakes. High temperature: Their high temperature properties make them more dependable during heavy use as they barely suffer from brake fade, they are also not prone to warping due to carbon fibers extremely low coefficient of thermal expansion (CTE). The CTE is actually ...

Been done with a polycarbonate type sheet. Actually I bought a solar collector with this type of cover. The sheet was formed with “pillow” type bulges to prevent sagging. About 5mm thick and strong enough to withstand hail etc as well as the high temperature from a panel heated when it has no water in it. Btw, don’t need the ordinary glass that is just a ...

My experience is that salt is not necessarily corrosive if kept dry. Moisture will interact with the salt if there is sufficient humidity. For your grinder objective, consider a coffee grinder using a burr mill. I've recently purchased a Mr. Coffee bean grinder that specifically notes that it's a burr mill design. I can grind with this burr mill ordinary ...

There are silicone specific adhesives, as silicone does not adhere well to any other material. Appropriately, there are rubber adhesives for genuine rubber as well. The method you describe is going to severely test the adhesion of the material, as it places the most stress along the weakest points in the system. Have you considered using surgical rubber ...
