A scaling law for large-deformation contact in soft materials
Tong Mu, Shizhuo Weng, Changhong Linghu +10
Compression of soft bodies is central to biology, materials science, and robotics, yet existing contact theories break down at large deformations. Here, we develop a general framew…
A tutorial on simulating nonlinear behaviors of flexible structures with the discrete differential geometry (DDG) method
Weicheng Huang, Zhuonan Hao, Jiahao Li +6
Flexible elastic structures, such as beams, rods, ribbons, plates, and shells, exhibit complex nonlinear dynamical behaviors that are central to a wide range of engineering and sci…
Rubber-to-glass adhesion between a rigid sphere and a shape memory polymer substrate of finite thickness
Changhong Linghu, Wentao Mao, Haoyu Jiang +2
Shape memory polymers (SMPs) are emerging as innovative smart adhesive materials with broad application potential. Compared to conventional elastomeric adhesives, SMP adhesives are…
Observation of strain-rate softening behavior in jammed granular media
Mingchao Liu, Weining Mao, Yiqiu Zhao +4
The strain-rate sensitivity of confined granular materials has been widely explored, with most findings exhibiting rate-strengthening behaviors. This study, however, reveals a dist…
