In a previous report a practical method of stability analysis was derived for axially compressed orthotropic cylinders. The method was based on upper and lower bounds to the critical load. However, in the analyses of these bounds the effects of transverse shear forces were neglected, and therefore the results were not applicable to cylinders of weak-core sandwich design. The analysis presented here modifies the previous analysis by inclusion of such effects. Numerical results for the two bounds are given in graphical form. Author
