Materials whose main structural component is a network of fibers are known collectively as Network materials and are ubiquitous in engineering and biology. Their strength is critical in many biological applications and industrial processes....
Flat, wrinkled, or ridged: Relaxation of an elastic film on a viscous substrate undergoing continuous compression [0.03%]
扁平、起皱或有脊的模式：弹性薄膜在连续压缩下的弛豫过程

Xianheng Guan et al.
We conduct a finite element computational study of the dynamics of a thin elastic film bonded to a much thicker viscous substrate undergoing compression at a fixed rate. The applied compression tends to continuously increase the strain, and...
Effects of tendon viscoelasticity on the distribution of forces across sutures in a model tendon-to-bone repair [0.03%]
肌腱粘弹性对模型肌腱骨修复中缝合处力分布的影响

Yuxuan Huang et al.
Tears to the rotator cuff often require surgical repair. These repairs often culminate in re-tearing when sutures break through the tendon in the weeks following repair. Although numerous studies have been performed to identify suturing str...

Fibrous gels such as cartilage, blood clots, and carbon-nanotube-based sponges with absorbed oils suffer a reduction in volume by the expulsion of liquid under uniaxial tension, and this directly affects crack-tip fields and energy release ...
The effect of edge compliance on the adhesive contact between a spherical indenter and a quarter-space [0.03%]

In this work, the effect of the edge compliance on the adhesive, frictionless contacts near the edge of a quarter-space is analyzed in terms of stress, deformation, and contact stiffness. The study relies on the numerical implementation of ...
Size Effects in Random Fiber Networks Controlled by the Use of Generalized Boundary Conditions [0.03%]
广义边界条件控制下的随机纤维网络中的尺寸效应

Structural transitions in some rod-like biological macromolecules under tension are known to proceed by the propagation through the length of the molecule of an interface separating two phases. A continuum mechanical description of the moti...
Shock-Induced Damage and Dynamic Fracture in Cylindrical Bodies Submerged in Liquid [0.03%]
液体中圆柱体的冲击损伤及动态断裂研究
