i want conclusion for process bending test

Solution

The system functions by using metal bending bars of varying thickness and stiffness todeform the test specimen. The force applied is measured by use of a built-in calibration andcalculation system. Due to the large margin of error from the measured andcalculated results, the experimental results are not acceptable for practicalapplication. At maximum deflection, the percentage of error of the experimentalresult for aluminium is 65% - 70%. One cause for this error occurs because the equations used are accurate in small deflections and loads easily handled by the material tested. The percentage error for steel is 60 % to 75 %. Also,Hooke\'s law is only valid for a portion of the elastic range for some materials, includingaluminium.
