Q1. A simple bar element is shown below. It is initially horizontal, with length L. Under some loading, the free end deforms by u in the x-direction and v in the y-direction. Show that the axial Green strain is: 1(u? + v EG L2 The displacement of the bar element free end is u=0.05, v=0.15 and the length is L=0.5, calculate the error in axial strain if the small strain formulation is used.
