Abstract

This technical note extends the validity of limit load solutions for thin-walled branch junctions, previously proposed by the current author, to thick-walled cases. It is achieved simply by re-normalizing the thin-wall expressions by the limit loads of thick-walled tubes instead of those of thin-walled tubes. Comparison with finite element results shows overall good agreement.
