most published results about the characteristics of niti wires are based on the mechanical laboratory tests on the as-received wires.the purpose of this study was to investigate the effect of saliva on load-deflection characteristics of superelastic niti wires.in this experimental study, 15 wires of three kinds of superelastic niti wires (sentalloy, force i and truflex) were prepared. five spec...

COMPARISON BETWEEN THREE-POINT AND FOUR-POINT FLEXURAL TESTS 2 TO DETERMINE WOOD STRENGTH OF EUCALYPTUS SPECIMENS 3 Paulo Ricardo Gherardi HEIN*, Loïc BRANCHERIAU 4 *Corresponding author: [email protected] 5 Received: September 21, 2016 6 Accepted: January 24, 2018 7 Posted online: January 25, 2018 8 9 ABSTRACT 10 11 Comparison between flexural wood strength values obtained from three-poin...

A flexural model of four-point bending fatigue that has been experimentally validated for human cortical bone under load control was used to determine how load and displacement control testing affects the fatigue behavior of human cortical bone in three-point and symmetric four-point bending. Under load control, it was predicted that three-point bending produced no significant differences in fa...

An efficient method for dominant point detection is proposed in this paper. The region of support for each point on curve is determined using bending value. The points with local maximum smoothing bending value can be located as the dominant points on the curve. The proposed algorithm needs no input parameter. The experimental results show that the new method is efficient and effective in detec...

the main objective of this study is to drive a simple solution for prediction of steel fiber reinforced concrete (sfrc) behavior under four point bending test (fpbt). in this model all the force components at the beam section (before and after cracking) are formulated by applying these assumptions: a bilinear elastic-perfectly plastic stress-strain response for concrete behavior in compression,...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...
