and suggested the importance of developing simple and
practical guidelines to determine crack orientation or
other techniques that could capture all the necessary
crack information such as the size, depth, density and
orientation of cracks needs to be used. Further studies are
necessary to understand whether there is a sp atial pattern
to crack orientations and whether there is a trend on the
distance be tween wid e cracks.
