Question

Problem 4.3, please

4.2 The following data were obtained during tensile tests on magnesium single crystals at room temperature 82 63 52 35 27 14 Tensile Yield Strength (psi) 402 155 121 100 148 258 36 41 63 Confirm the validity of Schmid's law for Mg and determine TcRss for this material. 4.3 Consider the single crystal having a simple cubic structure as discussed in Example Prob. 4.2. Repeat this problem for a situation where the tensile axis is parallel to the [011] crystal axis.

Problem 4.3 please and thank you

Answer 1

schuid's law T cess = sigma_yield cos lambda cos phi this law hold then sigma_yield x cos lambda cos phi should be constant. Schuld law Tcrss = plusminus 6 yield cos lambda cos phi it schuld law is valid then the lost column of the table should yield identnal data the actual data indeed centre an average critical data resolved shear stress of about 55 psi. hold approximately for mg
