Collapse mechanisms of sandwich panels with Miura-ori cores are analysed and classification the deformation regimes under three-point bending is proposed. It revealed that homogenisation approach to core material properties not applicable relatively strong origami due immediate simultaneous local deformations face sheets. To describe this regime, an analytical model based on development new stationary hinge lines in cells rigid motion rotation adjacent planes The pertains a single degree-of-freedom governed by global angle panel. On other hand, proved be analysis soft cores. This used analytically obtain collapse load related several modes. Parametric FE conducted further explore different sheet thicknesses. Experiments were validate finite element studies models. A good agreement between predicted forces those obtained simulations shown. Deformation mode maps constructed analyses terms thicknesses strength. brief comparison strength PVC honeycomb presented, demonstrating superiority loaded out-of-plane direction. possibility high shear strains metallic without damage gives them advantages compared low density foam

Thin-walled tubes with origami patterns exhibit good energy absorption capacity under axial tension. In this study, the tensile behavior of thin-walled pleated patterns, known as bellows, was first systematically investigated. A parametric study performed to assess impact and wall thicknesses on performance deformation mechanism bellows. The experimental numerical results showed that a desirable process without excessive initial peak force, followed by stable high plateau can be obtained. non-rigid deployment bellows tension is observed. specific increases unit width decreases provided value less than critical value. mean force increased pre-folding angle, maximum increase 16% in cases studied, thickness power 1.67. This provides new avenue for constructing an absorber energy-absorption loading.
