Consider the motion of a body given by
,
for times and where and are constants with dimension of length and is a constant with a dimension of time.
a) What constraints does the requirement of local invertibility place on constants and ?
b) Are the constraints you obtained above sufficient to ensure that the motion s a 1-1 mapping? Explain.
For the remainder of the problem assume that the reference domain is limited to , where .
c) Let us visualize the deformation for the special case . Consider a regular grid with spacing in the reference domain. Draw the shape of the deformed grid in the deformed configuration in the plane at times .
