I have tried the recommendations but still struggling to get the required results. Please find the attached Archive file of my structure for further recommendations. I would like to mention that the non linear data is actually extracted by using extensometer and used in this simulation.I have to delete the results and solution data from the attached file due to size of the file. I ave used 0.5-1 mm mesh size with 26 mm displacement. So your valuable recommendations will be highly appreciated.nn
