strain is defined by the ratio of change in dimension to the original dimension

here is the change in dimension meaning that the change in dimension that has been created after the deforming force has been removed ... or the change in dimension created when we are still holding with the force???

An example : when we are streching a rubber band we see an increase in length ....... but when we release it we see no net change in length ......... here what is the strain?????

Please reply
