AXIAL COMPRESSION OF SANDWICH CYLINDERS AND PANELS WITH CORRUGATED INTERLAYER AND ELASTIC FRAMES,
Abstract
The author derives expressions for determining the critical load on cylinders and panels with a corrugated interlayer under compression along the generatrices with transverse elastic framing members. Right circular cylinders and cylindrical and flat panels with outer sheeting of identical thickness are studied. A formula is derived for the potential energy of the entire cylinder, and differential equations are given for determining the minimum potential energy of the system as a whole during loss of stability. By subtracting the equations corresponding to the state of the cylinder before loss of stability from those corresponding to the state of the cylinder after loss of stability, a system of homogeneous linear equations is obtained which is used as a basis in deriving a dimensionless expression for the critical running force taking account of bending, tension and shear in the framing members.
