It may be embedded inside a composite material [5] and situated close to the internal defects.
The material along the gage length of the FBG-I may have been divided into several piecewise regions.
Conclusions Embedded FBGs in composite materials allows continuous on-line monitoring fatigue damage.

What’s worth attention was that the current-carrying coils would generate another magnetic field which affected the one produced by the permanent magnet materials of the actuators .
The permanent magnet material works more near to the MME point.

Marita Allan [2] proposed the study of thermal stresses, deformations and thermal fractures of backfill material, which would influence the heat transfer.
In order to simplify the problem and facilitates numerical calculation, the calculation based on the following assumptions: (1) Unfrozen soil is saturation state and frozen soil is as elastomer; (2) The material property is isotropic, soil particles does not occur deformation; (3) Volume change of water in the freezing process is ignored; (4) Influence of initial stress is ignored.
