| Abstract: | The derivation of an analytical m ethod to examine the stress field near the edge of a simply supported, lam inated beam is presented. Specific effort has been directed to accurately calculate th e transverse shear and normal stress by incorporating the exact displacem ent relations derived by Kozik (1970). A system of second order, ordinary, linear, non-homogeneous differential equations result, and a num erical and analytical technique is used for th eir solution. The m ethod is a versatile stress analysis procedure which can accom m odate any com bination of m aterial lay-up and any type of normal load on the upper an d lower surface. The reactions at the ends of the beam may be distributed in a fashion m ost accurately characterizing the physical supports. Three such distributions are considered. As a basis for comparison w ith B ernoulli-Euler and Timoshenko theory, an all steel lay-up is examined. To dem onstrate the m ethod's capability of analyzing lam inated beams, a two layered, steel ,/ alum inum lay-up is examined. The m eth o d can also be used to: 1 ) analyze homogeneous beams having small length to height ratios, and 2 ) determ ine the stress field near concentrated loads anywhere in the beam . |
