In order to characterize the mechanical behavior of thin polyimide films deposited on a GaAs substrate in a membrane configuration, bulging and nanoindentation tests are performed. By these means, Young’s modulus of polyimide films, with thicknesses on the micron scale is found to be equal to 2.8 GPa. These two different techniques, which do not rely on the same assumptions, give results in very good agreement. The tensile residual stress in the membranes due to the fabrication process is a decreasing function of the thickness: 12<σ0<25 MPa. These membranes are already employed as mechanical support for coplanar wave guides up to the millimeter wave range.

ABSTRACT This paper proposes a damaged viscoplastic model to simulate, for different isotherms (320, 350, 380, 400 and 420°C), the out-of-flux anisotropic mechanical behavior of Zircaloy-4 claddings in a stress relieved state over the fluence range 0-85.10$^{24}$ nm$^{-2}$ ($\rm E&gt;l$MeV). The model, identified from uni and biaxial tests conducted at 350 and 4000°C, is validated from tests made at 320, 380 and 420°C. This model is able to simulate strain hardening under an internal pressure followed by a stress relaxation period, since the loading produces an interaction between the pellet and the cladding (thermal creep). Both the integration of a scalar state variable, characterizing the damage caused by a bombardment with neutrons, and the modification of the static recovery law allowed us to simulate the fast neutron flux effect (irradiation creep).

A vibration method for the evaluation of the stress in a membrane is presented. The principle is based on the shift of the eigenfrequency of the modes due to the stress. The identification of the modes is obtained by an optical technique. The proposed method is applied to electrolytic nickel coatings. The results are compared with those obtained by X-ray
