Film bowing distortion
WebNov 18, 2009 · (3) At the edge of film, the principal molecular orientation axis begins gradually to tilt from the MD to the TD with rotation at the point where the bowing distortion increases rapidly, and afterwards gradually changes further more to the TD with an increase of actual stretching ratio. WebMay 1, 2003 · Bowing distortion is eliminated using transient differential heating during welding using the same welding conditions. Residual stress measurements are taken using the blind hole drilling method, and a comparison of residual stresses for the baseline stiffener and for the stiffener with transient differential heating is presented.

Webbowing is used under the assumption that it corresponds to the characteristic bowing. As shown in Fig. 3, bowing distortion (B)is expressed as the percentage of bowing distance DB divided by the film width L. When the film center lags behind the film edge, the bowing dis-tance DB is considered to be positive. B=DB/L×100 (%). (1) 2.4 ...
