The problem of escape from a locally stable attractor is ubiquitous in the natural sciences, and arises most notably in many nonlinear systems.
The parameter is the restitution factor and is usally associated with the material of rigid barrier.

Because the final shape of bending workpiece is related with the whole deformation process, the geometric parameter of die, material performance parameter will have great effect on springback.
Introduction The intellectualization of sheet metal forming involves control science, computer technology and sheet metal forming theory, so that it posses the characteristics of multi-subject crossover.

Experimental program Materials.
Table 1 shows properties of materials used in this study.
Cementitious materials were ordinary portland cement, granulated blast furnace slag, fly ash and silica fume.
Table 1 Properties of materials for concrete in this study.
In addition, concrete with all types of cementitious materials (hereafter, BFS30FA30SF20) was prepared.

With consideration that the properties of raw materials after reinforcing and repairing can basically meet the requirements of original design, correction is made incorporating with rebounding test of the main structural members prior reinforcing.
However, the material after reinforcing is determined according to current design value.
See Table 3 for properties of materials selected[6].

However, the serviceability and reliability of these materials depend greatly on the effect of residual stresses, the high level and the local gradient of which can lead to the initiation of cracks, reduction in corrosion resistance, etc.
