In general, strains applied on a material can change the internal electronic structure, thus affect electric, magnetic, and optical properties of the material, which has been demonstrated in different materials and structures.
Additionally, the nonlinear optical coefficients of telluride (ZnTe and CdTe) are much larger than that of other materials, showing their practical importance as nonlinear optical materials.
Elastic constants and piezoelectric constants of the involved materials are also obtained.
Telluride has remarkably high nonlinear optical coefficient compared with other materials, while its electro-optic constant is only one half of the value of ZnO. (2) It is obvious that the piezoelectric constants of the materials with Zinc-blende structures are almost one order smaller than that of the materials with Wurtzite structures.

Intensified internal leakages in the hydraulic cylinder, effected by leakages at the piston, can result from what follows: ageing of seal materials; contamination of the working fluid; parameters of the working fluid inconsistent with the system specifications, faults in the production technology.
Major causes of the hydraulic-circuit leaks are as follows: fatigue cracking of hydraulic pipes, tubes, hoses; leakages at hydraulic-line joints (improper hydraulic pipe-end extensions, excessive or too low assembly stress in pipe joints); faulty manufacturing of conduits (material faults, improper technology of conduit bending), mechanical damages to conduits (effects of faulty assembly of other structural components of an aircraft); others.

Introduction Since 0.2% MFIS was firstly found in Ni2MnGa single crystal in 1996 [1], Ni–Mn–Ga ferromagnetic shape memory alloys (FSMAs) have received more and more attention as potential magnetic actuator and sensor materials due to their large magnetic field induction strain (MFIS ) and high response frequency [2–4].
As is well known, the chemical composition of material significantly affects the Curie temperatures of Heusler-type Ni–Mn–Ga ferromagnetic shape memory alloy.
