Their buckling and post-buckling behavior, effects of dimensional variations, structural mass efficiency in carrying axial compression, and the influences from damaged units are studied in this work. The results show that cylindrical meta-shells can...

...Dezhong Tong; Andrew Choi; Jungseock Joo; Andy Borum; Mohammad Khalid Jawed When an overhand knot tied in an elastic rod is tightened, it can undergo a sudden change in shape through snap buckling. In this article, we use a combination of discrete differential geometry (DDG)-based simulations...

A microprobe’s critical buckling force not only dictates the microprobe resistance to buckling during insertion but also reveals the corresponding compliance during operation. The methods that are currently used to insert flexible microprobes into the brain are far...

...Hongyu Zhao; Yewang Su The prebuckling deformation of structures is neglected in most of the conventional buckling theory (CBT) and numerical method (CNM), because it is usually very small in conventional concepts. In the preceding paper (Su et al., 2019), we found a class of structures from...

However, increasing the microprobe stiffness may result in acute neural tissue damage during insertion. Moreover, any late or premature removal of the temporary stiffness after...

... flow through the tube. We observed that muscle force occasionally buckles the tube in a random fashion, i.e., similar muscles do not buckle the tube consistently. In order to explain this anomaly, here we develop an analytical model to predict the deformation and stability of circular elastic tubes...

The shell's wall thickness, and thus its stiffness, is tailored so as to obtain multiple controlled elastic...
