New transverse extension modes for buckling analysis of thin-walled members by using the constrained finite strip method
https://orcid.org/0000-0002-4245-2625
Abstract In this paper a new way to define transverse extension modes is introduced in the context of modal analysis of thin-walled members. The new transverse extension modes are inspired by the strain distributions of global and distortional modes. The new modes are employed here in the constrained finite strip method. The new modes require some change in the interpolation functions of the semi-analytical finite strip method, and this change is briefly discussed. The practical advantage of the newly proposed transverse extension modes is that the artificial stiffness increase, which is characteristic to pure global and/or distortional deformations in constrained analyses, can be compensated by the consideration of the relevant new transverse extension mode(s), as illustrated by numerous proof-of-concept examples in the paper.
Highlights Modal decomposition of thin-walled members is discussed. New transverse extension modes are introduced. The classic semianalytical finite strip method is slightly modified. The new transverse extension modes are implemented into the CUFSM software. Proof-of-concept examples are presented to illustrate the benefits from the new modes.
