A Model for Force Fluctuations in Bead Packs
, 1995 We study theoretically the complex network of forces that is responsible for the static structure and properties of granular materials. We present detailed calculations for a model in which the fluctuations in the force distribution arise because of ...

Research on the static contact angle algorithm of raindrop
Journal of Physics: Conference SeriesAbstract In the aerospace field, the raindrop spread is inhibited. After coming into contact with the wing wall, it rapidly contracts, and the surface energy is reconverted into kinetic energy, causing the raindrop to bounce off the surface. The main characteristic parameter of superhydrophobicity is the contact angle.

Advanced Engineering Materials, EarlyView.Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Defrosting Evolution Behavior and Drainage Characteristic on Superhydrophobic Surface
Zhileng xuebao, 2020 After traditional thermal defrosting, a great number of water droplets still retain on the surface, which can become the base of secondary frosting and accelerate secondary frosting. Therefore, duly removing retained droplets after defrosting is of great
