1.   The dashpot is used to denote the retarded nature of the response of a material to any applied stress.

2.   Any applied stress is now shared between the elements and each is subjected to the same deformation.

3.   Stress-relaxation experiments involve the measurement of the force required to maintain the deformation produced initially by an applied stress as a function of time.

4.   In a stress-relaxation experiment, the sample under study is deformed by a rapidly applied stress.
