Physical limits to sensing material properties

open access: yes, 2019
Constitutive relations describe how materials respond to external stimuli such as forces. All materials respond heterogeneously at small scales, which limits what a localized sensor can discern about the global constitution of a material.

Development of a model of contact shoe brake-drum interaction in the context of a mine hoisting machine [PDF]

open access: yes, 2017
Purpose. To develop models of contact brake shoe-drum interaction of a mine hoisting machine while braking, taking into account final bending stiffness of a beam and the effect of friction forces on the distribution of a contact pressure in it to make ...

Exploring the Application of Waxes and Their Mixtures Oleogels in Ice Cream

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The objective of this work was to produce ice cream using waxes oleogels, aiming to improve its nutritional value while maintaining its physical‐chemistry characteristics. Five ice cream formulations were manufactured using (1) milk fat, (2) canola oil, and (3–5) canola oil‐oleogels. The oleogels were produced with beeswax (BEW), carnauba wax (

Vibration of FG Shell Rested on Winkler Foundation [PDF]

open access: yes, 2020
Abstract Love’s first a pproximation theory is employed with the combination of Winkler term for the vibration of functionally graded cylindrical shell. MATLAB software is utilized for the vibration of functionally graded cylindrical shell with elastic foundation of Winkler and t he results are verified with the open literature.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Analysis of vibrations of beams on viscoelastic winkler foundations

open access: yes上海师范大学学报. 自然科学版, 2012
The complex modal analysis is applied to investigate vibrations of finite beams on viscoelastic Winkler foundations. The complex frequency equations and modal functions are obtained under simply supported boundary conditions.

The vibration of nanobeam resting on elastic foundation using modified couple stress theory

open access: yesTehnički Glasnik, 2018
In this paper, the vibration of nanobeams resting on the Winkler foundation is proposed using the modified couple stress theory. Hamilton’s principle is utilized to construct the governing equations.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.
