Abstract:

Research on sound-induced fatigue of flight vehicle panels is described. Primary emphasis is placed on the problems of panel response and panel strain concentration secondary mphasis is placed on e cquisi ion of fatigue data. Several panel designs w re consid red, inclu ing both idealized panels and panels of more practical design. P ROCEDURES FOR THE IMPROVEMENT OF SONIC FATIGUE RESISTANCE, AND FOR HE TESTING OF PANEL ITH IREN SOUN SOURC S HAVE BEEN DERIVED FROM THE STUDY. T eor ic l dor experimental studies are presented on lin ar response, angle-of-inci enc ff ct , sandwich construction, strain concentrations in sub tructures, nonlinear response, fatigue of notched panels, and fatigue at rivet lines.
