摘要: Abstract A membrane deflection technique has been developed to measure the isotropic residual stress in biaxially-constrained coatings. The demonstrated on various materials, including polyimide, latex rubber and photoresist Stress values obtained from compared well with results time-averaged vibrational holographic interferometry except for samples where rigidity effects were found be important. criterion based thickness, rigidity, sample radius is also discussed, establishing applicability of low rigidity.
