Modeling the kinematics and dynamics of compliant contact [PDF]
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004 In this paper, we discuss the modeling of the kinematics and dynamics of compliant contact between bodies moving in Euclidean space. First, we derive the kinematic equations describing the motion of the contact point when two rigid bodies are rolling on each other.

The relationship between contact resistance and contact force on Au coated carbon nanotube surfaces [PDF]
, 2007 Carbon-Nanotube (CNT) coated surfaces are investigated to determine the electrical contact performance under low force conditions. The surfaces under investigation are multi-walled CNTs formed on a Silicon substrate and coated with an Au film.

A Contact Model for Piezoelectric Beams [PDF]
, 2016 We consider a mathematical model which describes the equilibrium of an electro-elastic beam in contact with an electrically conductive foundation. The model is constructed by coupling the beam equation with the one dimensional piezoelectricity system obtained in [13].

What makes a young assertive bystander? The effect of intergroup contact, empathy, cultural openness, and in-Group bias on assertive bystander intervention intentions. [PDF]
, 2014 The present research tests the indirect effects of intergroup contact on adolescents’ bystander intervention intentions via four potential mediators: “empathy,” “cultural openness,” “in-group bias,” and “intergroup anxiety.” British adolescents (N = 855),

A contact model for rough crushable sand
Soils and Foundations, 2021 Sand roughness is now accessible to measurement. Incorporating this parameter into sand models using the discrete element method (DEM) is known to improve bulk small strain response.

Dynamic Friction-Slip Model Based on Contact Theory
Machines, 2022 In ultra-precision positioning equipment, the positioning accuracy is affected by the friction characteristics, especially the pre-slip stage. At present, the research on friction mainly includes contact theory and the dynamic friction process.
