Consider the plane deformation of the differential element ABCD defined by polar coordinates r, as shown

Consider the plane deformation of the differential element ABCD defined by polar coordinates r, θ as shown in the following figure. Using the geometric methods outlined in Section 2.2, investigate the changes in line lengths and angles associated with the deformation to a configuration A^′B^′C^′D^′, and develop the strain displacement relations:
