Q: What is the shear modulus of steel and silver? Please help! and state where you got it from...what site did you used? Thanks.: There are more than 10,000 different steel alloys that have been specified and used for different purposes. They cover a huge range of mechanical properties. For silver, are you talking about pure silver, or a silver alloy with a additives to improve its mechanical properties? Typical values for mild steel at room temperature are E = 210 GPa, G = 80 GPa (source: 30 years working as a mech. engineer) Wikipedia gives E = 80GPa, G = 30GPa for pure silver (temperature not specified). Silver alloys may be very different from those values. The properties will also depend on the metal forming process (e.g. drawn wire, annealed, etc). NB some alloys with silver in their common name contain no silver at all.

Q: How are steel coils inspected for formability using forming tests?: Steel coils are inspected for formability using forming tests to assess their ability to be shaped into desired forms without any defects or failures. These tests are conducted to evaluate the material's mechanical properties and determine its suitability for specific applications. Forming tests involve subjecting the steel coil to various forming operations, such as bending, deep drawing, or stretch forming. The coil is typically cut into specified dimensions and then subjected to these operations using specialized equipment. The key objective is to simulate the actual forming process that the steel will undergo in real-world applications. During the forming tests, several parameters are closely monitored. These include the amount of force or load applied, the rate of deformation, and the resulting strain or deformation experienced by the steel. Additionally, the coil's response to these operations is observed, including any visible defects like cracks, fractures, or surface imperfections. By carefully analyzing the performance of the steel coil during the forming tests, various formability characteristics can be determined. These include the material's resistance to deformation, its ability to withstand strain without failure, and its tendency to exhibit defects under specific forming conditions. The results obtained from these tests provide valuable insights into the suitability of the steel coil for specific forming processes and applications. Moreover, advanced techniques such as digital image correlation and strain analysis may be employed to precisely measure and evaluate the strain distribution across the steel coil's surface. These techniques help identify regions of the coil that experience higher strain and potential failure points. In conclusion, steel coils are inspected for formability using forming tests that simulate the actual forming processes they will undergo. These tests assess various formability characteristics, including the material's resistance to deformation and its propensity for defects. The results obtained from these tests aid in determining the suitability of the steel coil for specific applications and guide the selection of appropriate forming parameters.
