Buckling Behavior of FG-CNT Reinforced Composite Conical Shells Subjected to a Combined Loading

open access: yesNanomaterials, 2020
The buckling behavior of functionally graded carbon nanotube reinforced composite conical shells (FG-CNTRC-CSs) is here investigated by means of the first order shear deformation theory (FSDT), under a combined axial/lateral or axial/hydrostatic loading ...

Regional variation in digital cushion pressure in the forefeet of horses and elephants [PDF]

open access: yes, 2014
In this study, we seek to understand how the digital cushion morphologies evident in horse and elephant feet influence internal and external foot pressures.

Study of the Contact Characteristics of Machine Tool Spindle Bearings under Strong Asymmetric Loads and High-Temperature Lubrication Oil

open access: yesLubricants, 2022
The contact characteristics of angular contact ball bearings are closely related to the thermal failure of high-speed spindle systems. This paper establishes a closed-loop iterative model for analyzing the ball–race contact characteristics of machine ...

Combined loading of tractor's engine

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
The paper deals with influence of combined load of engine on drawbar properties of a tractor. The aim was focused on determination of power consumed via PTO and the impact on drawbar pull. During the development of the tractor is assumed that certain work will transfer operations from 60 to 60% over the PTO.

Impact resistance research of roadway support system under roof collapse

open access: yesMeikuang Anquan, 2022
To investigate the impact instability of the roadway support system caused by the collapse of the overlying hard roof strata during the coal mining process, and to guide the prevention and control of mine rock burst disasters, taking I010203 working ...

Origin of slow stress relaxation in the cytoskeleton

open access: yes, 2019
Dynamically crosslinked semiflexible biopolymers such as the actin cytoskeleton govern the mechanical behavior of living cells. Semiflexible biopolymers nonlinearly stiffen in response to mechanical loads, whereas the crosslinker dynamics allow for ...

On combinations of random loads

open access: yesAdvances in Applied Probability, 1980
Structures are subject to changing loads from various sources. In many instances these loads fluctuate in time in an apparently random fashion. Certain loads vary rather slowly (called constant loads); other loads occur more nearly as impulses (shock loads).

Load combination of permanent and variable loads

open access: yesRakenteiden Mekaniikka, 2018
This paper concentrates on the combination of permanent and variable loads in the structural probability theory and its implementation in codes. In the current codes, the permanent and variable loads are sometimes combined independently, and sometimes they are combined dependently.
