Unformatted text preview: Sheet1 Page 1 If you recall in lab, the hot-rolled steel was not picking up correct transverse extensometer readings so when that was put bac numbers were not re-zeroed. When analyzing hrs.raw, for axial strain use: (Ext1(V)-160)*0.05 and for transverse strain use: (Ext2(V)-0.003324)*250/D0 This should get you a Poisson's ratio in the appropriate ballpark for steel and never exceeding 0.5 (incompressible). For crs.raw, note that the columns are different and the data system may have tried to give converted values. For this, to get axial strain use: Ext.1(%e)/100 and for transverse strain use: Ext.2(%e)/100*0.4 This should get you a Poisson's ratio in the appropriate ballpark for steel and never exceeding 0.5 (incompressible). As I will be the one grading your reports, it's important you use the above calibrations. Matthew Manley Hi everyone, Two quick things: 1) The data at the very end for the hot- and cold-rolled steel may have been where the transverse and axial extensometers ha If you see any discontinuities, this is the case and that end data should not be used for finding Poisson's ratio. If you see any discontinuities, this is the case and that end data should not be used for finding Poisson's ratio....
