An offset of strain equal to given permissible plastic strain, eg at 02% for Al, is marked on the x axis of the stressstrain curve, and a straight line is drawn through this point which is parallel to the initial stressstrain curve The intersection of straight line with the stress strain curve gives design stress called PROOF STRESSThe Offset Method The offset is the horizontal distance between the modulus line and any line running parallel to it For example, the line CD in Figure 2 is "offset" from the modulus line by 02% (0002 in/in) The value of the offset for a given material is usually expressed this way Yield Strength, 01% or 02% OffsetFor a 02% offset x is 002 when y=0 For a parallel line the slope (determined by 4232 in the formula) cannot be changed so the constant must be, from 0701 to 7763 A further data set can be created with the altered constant and added to the chart as before Ocw Tudelft Nl Wp Content Uploads Materiaalkunde 1 Slides Chapter6 Pdf 0.2 offset yi...
