The primary application of the notched three point bending test (3PBT) is to determine fracture energy concrete. However, measurement setup also suitable for determining additional mechanical parameters: flexural tensile strength, modulus elasticity, and indirectly compressive strength also. aim this paper present calculation methods properties that can be determined from results a series in wh...

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...

Lower limbs are normally the first contacted body region during car-pedestrian accidents, and easily suffer serious injuries. The previous tibia bending tolerances for pedestrian safety were mainly developed from three-point bending tests on tibia mid-shaft. The tibia tolerances of other locations are still not investigated enough. In addition, tibia loading condition under the car-pedestrian i...

Strength of both muscles and bone are important for fracture prevention in osteoporotic individuals. Therefore, drugs that are preclinically tested in animals for preventing or treating osteoporosis, and reducing fracture risk, should not only be checked for their effects on bone strength, but also for those on muscle strength. We developed a rat model to measure both in the same animal, using ...

The objective of this study is to evaluate the existing test methods of die strength, including widelyaccepted three-point and four-point bending tests, and a newly-proposed point-load test by testing silicon die specimens with different surface conditions. It has been reported that there are three factors to influence die strength: the surface conditions of the die (including grinding-mark dir...

This study investigated the influence of porosity on the flexural property of a nanoporous alumina film. When the porosity of the alumina film increased, both bending strength and modulus declined. The results from the bending test revealed that the setting of the film during the bending test had significant influence on the flexural property. Fracture only occurred when the porous side of the ...
