One FBG is fixed on tested object, its wavelength is, and the other one is fixed on constructional element which has same material and temperature field, its wavelength is.
Selection of the material is crucial to the property of elastic component.
Material of the elastic component must have the feature of high elastic limit, small elastic hysteresis, corrosion resistant, good capability for machining, high fatigue limit and economical efficiency.

Experimental Materials For the preparation of film, we used PBAT (poly (butylene adipate-co-terephthalate)) produced by BASF, under the brand name: PBAT Ecoflex® F Blend C1200, Orange oil acquired from World of Oils, and Quimex chloroform PA was used as the solvent.
This rheology indicates the internal behavior of the materials [10].
The specific deformation is a measure of the elongation of the material until its rupture [20].

Shot chosen for industrial application is often as hard as the impacted target material.
Following numerical validation, a parametric study was conducted to investigate the effect of shot and target parameters on the residual stress pattern including shot size, impact velocity and angle; target material properties (initial yield stress, strain hardening, strain rate dependent material); multiple shot impacts; and peening coverage [7,8].
Whilst FE can successfully model the complex interaction between the material non-linearity with the non-linear contact in shot peening, it cannot model a stream of many discrete shots impacting on a surface.
