Characteristics of Stresses in Three Spar Box Beam and Its Torsion Center

1979 The Journal of the Japan Society of Aeronautical Engineering  
Stresses in the single bayed three spar box beam are obtained from Eqs. (2.5), (2.6) and so on . By transforming them into Eqs . (2.25), (2.26), the higher approximation is given as expressed by Eqs. (2.32), (2.33) and reduced to Eqs . (2.35),
