Static Test of Flexo Compression in Posterior Thoracolumbar Spinal Fixation with Conical Cylindrical Screws

Global Spine Journal, 2016
Introduction The aim of this paper is to describe the results obtained of a static test of flexo compression in polyaxial transpedicular conical cylindrical screws; which we have used for more than 20 years; in posteriors thoracolumbar spine fixings ...

Optimization of applied loads for assessing load-velocity relationship during back squat.

PLoS ONE
PurposeThis study aimed to identify the lightest load to validate the load-velocity (L-V) relationship in the back squat using the modified multiple-point (a lower highest load compared to the standard method) and in-field two-point methods ...

A proposal of an inverse analysis method for estimating nonlinear stress-strain relation from three-point bending test

Nihon Kikai Gakkai ronbunshu, 2015
An inverse analysis method was proposed for estimating nonlinear stress-strain curve with plastic deformation from load-deflection curve of three-point bending test of simply supported beam with rectangular cross section. This method was based on a small

Strain-stress experimental behaviour of tapered columns in single-span frames/Trapecinių kolonų vienanaviuose rėmuose deformacijų-įtempių būvis

Journal of Civil Engineering and Management, 2000
Two single-span frame tests were carried out. The width of frame is 6m, column's height 4.17m. Frame supports are pinned. Connection between column and beam is rigid. Beam of the frame was loaded with two vertical and one horizontal loads.

Experiment and Calibration of Finite Element Parameters of Pineapple Based on Cohesive Zone Model

Agriculture
In view of the lack of research on the extrusion of pineapple caused by the overall stress response of pineapple at the present stage of pineapple automatic harvesting, the finite element model of pineapples can be studied by constructing such a model ...

Influence of loading point on the static bending test of wood

Journal of Wood Science, 1998
We conducted three-point bending tests by changing the condition at the loading point and then examined the influence of the loading point on the test data. Yellow poplar (Liriodendron tulipfera L.) was used for the tests. First, using loading noses with various radii, static bending tests were conducted by varying the depth/span ratios.

Estimation of Uniaxial Compressive Strength and Tensile Strength of Sandstone Based on Point Load

Renmin Zhujiang
In rock mechanics and engineering practice, accurate and rapid evaluation of uniaxial compressive strength and tensile strength of rock is important for engineering design and construction safety. Traditional test methods are time-consuming and laborious,
