Non Smooth Contact Dynamics Approach for Mechanical Systems Subjected to Friction-Induced Vibration

Lubricants, 2019
The modeling of contact is one of the main features of contact dynamics in the context of friction-induced vibrations. It can have a strong impact on the numerical results and consequently on the design choices during the optimization or specification of

Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities

Advanced Functional Materials, EarlyView.
We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Pin-on-Disc Experimental Study of Thermomechanical Processes Related to Squeal Occurrence

Lubricants
Squeal refers to a sustained high-intensity noise resulting from friction-induced vibrations. Although it is known that it originates from mode coupling, the conditions under which it occurs are still unclear, especially regarding the contact conditions.

Sensitivity studies of friction-induced vibration

International Journal of Vehicle Design, 2009
Friction-induced vibration is notoriously twitchy. This paper examines the origin of the sensitivity, using a model with two linear systems coupled at a single-point sliding contact where a general linearised model for dynamic frictional force is allowed.

Experimental Evaluation of Brake Pad Material Propensity to Stick-Slip and Groan Noise Emission

Lubricants, 2018
Frictional and dynamic responses of brake pad materials, when sliding on brake disc counterfaces, are at the origin of noise, vibration and harshness (NVH) issues such as brake noise emissions.
