Effects of stretching on the frictional stress of rubber [PDF]

open access: yes, 2017
In this paper, we report on new experimental results on the effects of in-plane surface stretching on the friction of Poly(DiMethylSiloxane) (PDMS) rubber with smooth rigid probes.

A Study of Static and Dynamic Mechanical Behavior of the Substrate in Ultrasonic Consolidation [PDF]

open access: yes, 2006
A new 2-D FEM model is developed for a fundamental study of the time dependent mechanical behavior of the substrate in ultrasonic consolidation. The simulation shows that for a given vibration condition, the amplitude of contact friction stress and ...

Cohesive, frictional powders: contact models for tension [PDF]

open access: yes, 2008
The contacts between cohesive, frictional particles with sizes in the range 0.1–10 μm are the subject of this study. Discrete element model (DEM) simulations rely on realistic contact force models—however, too much details make both implementation and ...

A microscopic theory for discontinuous shear thickening of frictional granular materials [PDF]

open access: yes, 2017
We extend a recent theory for the rheology of frictionless granular materials [K. Suzuki and H. Hayakawa, Phys. Rev. Lett. 2015, 115, 098001] to the case of frictional disks in two dimensions.

Study of Frictional Effects of Granite Subjected to Quasi-Static Contact Loading

open access: yesLubricants, 2020
The rock fragmentation response to drilling, in particular percussive drilling, is important in order to improve the efficiency of such an operation. The resulting problem includes spherical contact between the drill bit and the material and therefore, a

Predicting frictional aging from bulk relaxation measurements

open access: yesNature Communications, 2023
The coefficient of static friction between solids normally increases with the time they have remained in static contact before the measurement. This phenomenon, known as frictional aging, is at the origin of the difference between static and dynamic ...

Estimation of the normal contact stiffness for frictional interface in sticking and sliding conditions [PDF]

open access: yes, 2019
Modeling of frictional contact systems with high accuracy needs the knowledge of several contact parameters, which are mainly related to the local phenomena at the contact interfaces and affect the complex dynamics of mechanical systems in a prominent ...

Thermomechanical analysis of an elastoplastic rough body in sliding contact with flat surface and the effect of adjacent contact asperity

open access: yesAdvances in Mechanical Engineering, 2015
The study of the instantaneous frictional temperature, stress, and equivalent plastic strain generated when two surfaces are in frictional sliding process plays a significant role in understanding friction and wear mechanism.

Formulae for frictional resistance considering mud thixotropy and pipe-soil contact characteristics

open access: yesYantu gongcheng xuebao, 2017
The jacking force is the crucial parameter for the design and construction of pipe jacking projects. It is controlled by the lateral frictional resistance of pipe jacking and affected by the characteristics of pipe-soil contact and pipe-mud contact.
