Force cycles and force chains

Physical Review E, 2010
We examine the coevolution of N cycles and force chains as part of a broader study which is designed to quantitatively characterize the role of the laterally supporting contact network to the evolution of force chains. Here, we elucidate the rheological function of these coexisting structures, especially in the lead up to failure.

Force Calibration in Lateral Force Microscopy

Journal of Colloid and Interface Science, 2000
An analysis of the contact mechanics and the forces of interaction in lateral force microscopy measurements is presented. This analysis allows for a new method of interpretation of the frictional forces, the lateral contact stiffness, and the contact shear strength.

Ensemble Force Spectroscopy by Shear Forces

Journal of Visualized Experiments, 2022
Single-molecule techniques based on fluorescence and mechanochemical principles provide superior sensitivity in biological sensing. However, due to the lack of high throughput capabilities, the application of these techniques is limited in biophysics. Ensemble force spectroscopy (EFS) has demonstrated high throughput in the investigation of a massive ...

Force Elements and Reaction Forces

2015
In the present chapter some of the most relevant applied forces and joint reaction forces are introduced. There are many types of forces that can be present in multibody systems, such as gravitational forces, spring-damper-actuator forces, normal contact forces, tangential or frictional forces, external applied forces and moments, forces due to ...

Optimal force, differential force, and anchorage

American Journal of Orthodontics, 1969
Abstract 1. 1. When applied to canine retraction for a clinically useful period of time, there are no data to support the theory of optimal force. 2. 2. The logical derivative of this theory, differential force as it is currently employed, could not be substantiated in the present study. 3. 3.

Tendon Forces Balancing a Force on the Fingertip

Journal of Biomechanics, 1982
Many problems in which muscle or tendon forces must be calculated are indeterminate. Finding tendon forces balancing a force on the fingertip is such (static) problem. Several criteria are possible for the optimization of these tendon forces.

Forced Oscillations with Nonlinear Restoring Force

Journal of Applied Physics, 1953
Forced oscillations with nonlinear restoring force are studied in transient states as well as in steady states. The original differential equation characterized by a nonlinear term is transformed under certain restrictions to the following differential equation of the first order: dy/dx=Y(x,y)/X(x,y).
