WebFor a long (slender) column, buckling occurs way before the normal stress reaches the strength of the column material. For example, pushing on the ends of a business card or bookmark can easily reproduce the buckling. For an intermediate length compression member, kneeling occurs when some areas yield before buckling, as shown in the …
