Buckling of knitted fabric wrapped around a rigid cylinder
Kotone Tajiri, Tomohiko G. Sano
Knitted fabrics exhibit high flexibility due to their periodic loop structures formed by bent yarns. Under compressive loading, they develop three-dimensional (3D) wrinkling patter…

(Dis)continuous buckling transition in elastic shell mediated by contact
Takara Abe, Tomohiko G. Sano
Snap-buckling is a rapid shape transition in slender structures, appearing as a fundamental switching mechanism of natural and man-made systems. Boundary conditions of structures a…

Twist deformation of physical trefoil knots
Taiki Goto, Shunsuke Nomura, Tomohiko G. Sano
Knots across various length scales, from micro to macro-scales, such as polymers, DNA, shoelaces, and surgery, serving their unique mechanical properties. The shape of ideal knots…
