“…19,20 developed a stereo camera mechanical system for measuring strain inside agricultural tires, estimating tire forces and capturing 3D contour of rolling. Aakash 21 applied the DIC technique to measure dynamic characteristics of racing tires in the rolling conditions. The strains and displacements of tire sidewalls were obtained to reveal the conflicting mechanisms between noise, dry grip performance and rolling resistance by using the VIC-3D measurement system in the process of the tire rolling state.…”

The rolling and sliding state of the tread rubber material within contact patch was very important to the handling stability and safety of the vehicle. In this paper, first, the absolute coordinate system was introduced into the digital image correlation method, which improved the ability of the traditional digital image correlation method to solve the large deformation of polymer material surface. Second, a new calculation method of rolling friction coefficient based on the brush model was proposed. Third, a non‐contact full‐field rolling dynamics experimental device was developed to study the effects of carbon black components, rotational speed and vertical load on the rolling mechanical characteristics of tread rubber material. On this basis, the rolling mechanical characteristics of tread rubber material with different formulations were obtained by analyzing the distribution properties of global strain rate, full‐field longitudinal speed and full‐field longitudinal acceleration and the variation laws of transverse/longitudinal strain rate, trajectory of marked points, stress‐strain hysteresis curve and rolling friction coefficient. Finally, the influence mechanism of carbon black composition on rolling mechanical properties of tread rubber material was revealed.

“…Similarly, although the principles of stereo or multi-view photogrammetry have matured in the last century, a plethora of photogrammetry methodologies have appeared recently for structural dynamics [1]. Methods can be broadly classified into three categories, depending on the tracking approach used: point-tracking (PT) [3,4,[15][16][17][18], digital image correlation (DIC) [3,5,6,[19][20][21][22][23][24][25][26][27], and target-less approaches. Stereo Photogrammetry principles have been recently adopted for achieving 3D vibration measures combining a single high-speed camera with a simpler mass-market still camera [28], whereas the pros and cons of a multi-view approach have been recently discussed in [29].…”

“…With the advances in optical techniques, researchers have started to use digital image correlation (DIC) and photogrammetry for structural health monitoring 20 and nonintrusive vibration measurements 21 for mechanical components. [22][23][24][25][26][27][28][29][30][31][32][33][34] The optical techniques have also been used for full-field deformations in the biomechanical field. 35,36 Evans and Holt 14 used an optical technique to study mechanical properties of human skin and validate finite element results.…”

Vibration analysis of healthy skin: toward a noninvasive skin diagnosis methodology,"Abstract. Several noninvasive imaging techniques have been developed to monitor the health of skin and enhance the diagnosis of skin diseases. Among them, skin elastography is a popular technique used to measure the elasticity of the skin. A change in the elasticity of the skin can influence its natural frequencies and mode shapes. We propose a technique to use the resonant frequencies and mode shapes of the skin to monitor its health. Our study demonstrates how the resonant frequencies and mode shapes of skin can be obtained using numerical and experimental analysis. In our study, natural frequencies and mode shapes are obtained via two methods: (1) finite element analysis: an eigensolution is performed on a finite element model of normal skin, including stratum corneum, epidermis, dermis, and subcutaneous layers and (2) digital image correlation (DIC): several in-vivo measurements have been performed using DIC. The experimental results show a correlation between the DIC and FE results suggesting a noninvasive method to obtain vibration properties of the skin. This method can be further examined to be eventually used as a method to differentiate healthy skin from diseased skin. Prevention, early diagnosis, and treatment are critical in helping to reduce the incidence, morbidity, and mortality associated with skin cancer; thus, making the current study significant and important in the field of skin biomechanics. © The Authors.
