Problem 1: Deflection of a sandwich beam with distributed load according to the method of partial deflections For the sandwich beam shown in Fig. 6, determine the bending line u(x) and the maximum value of the deflection. It is assu- med that the beam has thin face sheets and a soft core. Fur- thermore, generally derive the ratio of partial deflections and evaluate your result in addition for the values L = 2000 mm, Ahk = 150mm, AhP = 5mm, ED = 74000 MPa and G 11 MPa.
