Given the 9 deformed elliptical pebbles (i=1-9) in Figure 12.33 (below), estimate the orientation and shape of the strain ellipse. Instructions: Draw the long axis (La) and short axis (Sa) of each pebble. Determine the final shape ratio (R;) for each pebble (Note: Rf = (La)/(Sa). Find the orientation of the long axis of each pebble (0';) with respect to the lower, long edge of Figure 12.33 (this is the reference line!). NOTE: The La and Sa of pebble 1 is already done for you!. The long axis is extended to interest the lower edge of the image to define the acute angle 0', .You do the La and Sa for other ellipses!

Question
Transcribed Image Text:Given the 9 deformed elliptical pebbles (i=1-9) in Figure 12.33 (below), estimate the orientation and shape of the
strain ellipse.
Instructions:
Draw the long axis (La) and short axis (Sa) of each pebble. Determine the final shape ratio (R;) for each pebble
(Note: Rf = (La)/(Sa).
Find the orientation of the long axis of each pebble (0';) with respect to the lower, long edge of Figure 12.33 (this is
the reference line!).
NOTE: The La and Sa of pebble 1 is already done for you!. The long axis is extended to interest the lower edge of
the image to define the acute angle 0', You do the La and Sa for other ellipses!
