- Laboratory buckling tests of strings was reported and the results were compared with theoretical formulas. The findings implied that the process of string buckling can be divided into two stages, specifically plane buckling and spatial buckling. In the spatial buckling, the string-buckling configuration can be illustrated by helical buckling theories. The friction between the string and the wall of the confining tube rendered an irregular buckling shape and prohibited further buckling at some critical loads. The buckling theories do not account for this effects. Thus, an approximate formula for estimating the friction force was proposed, which provided more exact results.
