• The experimental model is a method for carrying out load and unloading in air jet on the surface of the flexible materials. It is possible that this method carries out load and unloading in a moment, and dent deformation which arose on the surface can be measured in the laser beam in a moment. In addition, the aging variation of shape and dimension of the dents can be measured also. In this study, the fact of the following has done using creep meter and experimental model. Under the monotonic step load, three behaviors were shown elastic behavior, retarded elasticity behavior and viscous flow from the instant dents deformation. The formulation of dents depth under the creep load was able to be formulated. In addition, the experimental result under the step load repeatedly agreed with calculation result using the principle of superposition.
