The aim of this paper is to study the bending properties of tail flukes of a dolphin. The bending test was carried out to obtain the displacements on different test points of a fluke. The Young’s moduli of the ligamentous layer and the dense connective tissue in the flukes were obtained from the tensile test and the compression test. In order to establish an FEM model for bending deformation of...

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...

Longevity of cut flowers of many gerbera cultivars (Gerbera jamesonii) is typically short because of stem bending; hence, stem bending that occurs during the early vase life period is a major problem in gerbera. Here, we investigated the effects of sodium nitroprusside (SNP) on the delay of stem bending in the gerbera cultivars, Alliance, Rosalin, and Bintang, by examining relative fresh weight...

In the process of research and development of tube bending forming technology, the way of improving the forming quality and establishing the optimization of forming process parameters has become an important problem that should be solved quickly. This text simulated the process of bend forming with the way of finite element, combined with the effects of geometric and physical parameters on the ...

Abstract--L-shaped beams subjected to pure elastic-plastic bending are investigated thoroughly. The shifting and rotating of the neutral axis of the beam during bending and springback after unloading are described mathematically, while the curvatures of the beam before and after springback are given. The method proposed in this paper is valuable both to the further theoretical studies of the as...

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,...

We investigated the microstructural and fatigue characteristics on consolidated Japanese cedar called “ObiSugi (Cryptomeria japonicain)” fabricated by hot-pressing. Hot-press treatment was conducted at various conditions. Three point bending test, hardness test and plane bending fatigue test of consolidated wood were carried out to investigate mechanical properties. Flexural strength of consoli...
