Description
Zuoquan Zhu and four co-authors analyze heat-driven buckling in beams strengthened with folded graphene, in this 2026 paper. Graphene origami folds tiny carbon sheets into springy shapes that can stiffen a composite. Engineers need to know when a hot beam will suddenly bow out of line, a failure called thermal buckling.
The team built a model that joins classic beam theory with a Hamiltonian frame, turning the buckling question into an eigenvalue problem with tidy math. They derived formulas for the critical heat load and the buckled shapes, counting how the filler runs through the beam's depth. Tests of the formulas showed layout of the filler mattered most. Higher fold levels and higher temperatures lowered the safe load. Smart placement of the folded sheets can thus buy back strength, a guide for designers of light, hot structures.
