Residual stress film thickness
WebThe films further comprise a patterned adhesive layer. The thermoplastic films, when tested by a 25% Heat Relaxation Test at a thickness of about 0.006 inches, exhibit a final load from about 0.02 to about 0.3 pounds force; and when tested by a 25% Elastic Recovery test, exhibit a residual strain at one minute of 2% or greater. WebApr 2, 2015 · Secondly, the residual stress generally increases with the thickness of metallic film (Hu et al., 2011; Liu et al., 2016a). Thus, the residual stress of thinner layer is smaller …
