Airys stress function -- structures

  1. Jan 13, 2015 #1
    1. The problem statement, all variables and given/known data
    For (fi)= (b/6) x*y3 +C*xy show that simply supported beam of 2L loaded concentrated load at mid span.,the stress function satisfy loading condition is (fi) .treat concentrated load as shear stress suitably distributed to shoot this function. so that intergtal of limit (h to -h) for stress stress (tou)xy= (-W/2) ..
    2. Relevant equations
    see attachment
    3. The attempt at a solution
    boundary conditions 1. (sigma)yy=0 for y =h to -h
    to remove constants in stress function i need one more boundary condition .. ?? any help ll be apreciated . thanks

    i found other boundary condition too ..beam shear stess (tou)xy=o at y=(-h &=+h)..thanks anyway ..
