The Anatomical Record, EarlyView.Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Effect of boundary conditions and constitutive relations on the free vibration of nonlocal beams
Results in Physics, 2020 The free vibrations of nonlocal Euler and Timoshenko beams have been studied extensively, but there still remain some problems concerning boundary conditions and constitutive relations.

Chemistry–Methods, EarlyView.The experimental setup presented in this work combining laboratory‐based X‐ray absorption spectroscopy with an electrochemical reactor advances the fundamental understanding of electrocatalysts at extended time scales. By the example of the electrochemical reduction of CO2, the parameters are discussed that are relevant for optimizing the system to ...

Static and Dynamic Responses of Micro-Structured Beams
Applied Sciences, 2020 In this study, we developed a one-dimensional Timoshenko beam model, embedded in a 3D space for static and dynamic analyses of beam-like structures. These are grid cylinders, that is, micro-structured bodies, made of a periodic and specifically designed ...

Peridynamic Solutions for Timoshenko Beams
Engineering, 2014 Peridynamics is a recently developed formulation for continuum mechanics which describes material deformation using a nonlocal approach. Unlike Classical Continuum Mechanics (CCM) where the conservation equations are cast into partial differential equations, Peridynamics describes the deformation in terms of integro-differential equations ...

Micropolar modeling approach for periodic sandwich beams [PDF]
Compos. Struct. 2018;185:656-664, 2018 We develop a micropolar Timoshenko beam theory and use it to model web-core sandwich beams. The beam theory is derived by a vector approach and the general displacement solution to the governing sixth-order equations is given. A nodally-exact micropolar Timoshenko beam element is formulated using the solution.

Pressure–impulse diagrams of RC beams considering fire–blast interaction
Structural Concrete, EarlyView.Abstract When analyzing military, defense, or structures/infrastructures deemed critical, explosion‐induced actions—often associated with malicious actions—play a significant role. The combined effect of a blast and fire is not uncommon: in fact, an explosion can be the extreme consequence of a fire or vice versa, a fire can occur as the result of an ...
