Global Buckling of Sandwich Columns and Wide Panels
The most important issue regarding buckling of sandwich structures is the effect of transverse shear which can significantly reduce the Euler critical load. Simply put, the effect of transverse shear absolutely cannot be neglected. Therefore, all formulas for sandwich buckling are essentially ways to include this effect into the Euler formulas. Two basic ways for including transverse shear in column buckling are the Engesser (1891) and the Haringx (1948, 1949) approaches. Both of these approaches are also outlined by Timoshenko (1936).
