The force which acts on an object without coming physically in contact with it is called non contact force. Learn about its types i.e. Gravitational Force, Magnetic Force & Electrostatic Force.
The fretting fatigue live depends on local stresses and the relative displacement. The proposed (MMR) can describe the behavior in the fretting fatigue conditions.关键词: Contact forces Fretting fatigue life Crack and initiation site DOI: 10.1016/j.triboint.2011.12.008 被引量: 11 ...
Atomic force microscopy contact forces are shown to obey a Poisson distribution, so that the ratio of their variance to mean gives the force of a single chemical bond between the tip and sample. The derived single-bond force was able to distinguish nominal van der Waals interactions (60 ± ...

Non-conformal contact constraints, widely used in engineering applications, are formulated in terms of surface parameters, referred to as non-generalized coordinates. For each contact between two rigid bodies, five contact constraints, written in terms of generalized and non-generalized coordinates, are...
Models and simulation of both robots are discussed, as well as occurring forces during collisions of the BioRob-X4 arm with the ground. We are also able to demonstrate good agreement of ground contact forces measured during slow jogging motion of a human subject with simulation results obtained ...
The examination of the evolution of the forces, velocities and displacements during the collision emphasizes the importance of correct accounting for non-linearity in the contact model and micro-slip effects. It also demonstrates how these phenomena need to be considered into the model in order to ...
The implementation of video-based non-contact technologies to monitor the vital signs of preterm infants in the hospital presents several challenges, such as the detection of the presence or the absence of a patient in the video frame, robustness to changes in lighting conditions, automated identifi...
Self-contact modeling on beams experiencing loop formation Many engineering scenarios involve contact between beam structures or, eventually, self-contact. Specifically when dealing with a beam submitted to large t... AG Neto,PDM Pimenta,P Wriggers - 《Computational Mechanics》 被引量: 29发表: 2015...
