Abstract : The AIAA/ASME/ASCE/AHS/ASC 31st Structures, Structural Dynamics and Materials (SDM) Conference was held on April 2-4, 1990 in Long Beach, California. This publication is a compilation of presentations of the work-in-progress sessions and does not contain papers from the regular sessions since those papers are published by AIAA in the conference proceedings. Partial contents include: (1) TEST/SEMI-EMPIRICAL ANALYSIS OF A CARBON/EPOXY FABRIC STIFFENED PANEL; (2) REPEATED BUCKLING OF COMPOSITE SHEAR PANELS; (3) COMPRESSIVE FAILURE OF THICK-SECTION COMPOSITE LAMINATES WITH AND WITHOUT CUTOUTS SUBJECTED TO BIAXIAL LOADING; (4) ANALYTICAL SOLUTION FOR THE ELASTOPLASTIC RESPONSE OF A CONTINUOUS FIBER COMPOSITE UNDER UNIAXIAL LOADING; (5) THE LOOPED ADHESIVE STRIP: AN EXAMPLE OF COPLANAR DELAMINATION INTERACTION; (6) A NEW BEAM THEORY USING FIRST-ORDER WARPING FUNCTIONS; (7) PROBABILISTIC STRUCTURAL ANALYSIS BY EXTREMUM METHODS; (8) PROBABILISTIC FAILURE ASSESSMENT WITH APPLICATION TO SOLID ROCKET MOTORS; (9) EVALUATION OF ALTERNATIVES FOR BEST-FIT PARABOLOID FOR DEFORMED ANTENNA SURFACES; (10) COMBINED DESIGN OF STRUCTURES AND CONTROLLERS FOR OPTIMAL MANEUVERABILITY; (11) GROUND TEST PROGRAM FOR NEW ATLAS PAYLOAD FAIRINGS; (12) DIRECT USE OF LINEAR TIME-DOMAIN AERODYNAMICS IN AEROSERVOELASTIC ANALYSIS: AERODYNAMIC MODEL; (13) COMPUTATION OF MAXIMUM GUST LOADS IN NONLINEAR AIRCRAFT USING A NEW METHOD BASED ON THE MATCHED FILTER APPROACH AND NUMERICAL OPTIMIZATION; (14) PIEZOELECTRICALLY FORCED VIBRATIONS OF ELECTRODED DOUBLY ROTATED QUARTZ PLATES BY STATE SPACE METHOD; and (15) ANALYSIS OF ELASTICALLY TAILORED VISCOELASTIC DAMPING MEMBER.
