Effect of Printing Layer Thickness and Postprinting Conditions on the Flexural Strength and Hardness of a 3D-Printed Resin

BioMed Research International, 2022
Background Recently, dentists can utilize three-dimensional printing technology in fabricating dental restoration. However, to date, there is a lack of evidence regarding the effect of printing layer thicknesses and postprinting on the mechanical ...

Influence of Fiber Volume and Fiber Length on Thermal and Flexural Properties of a Hybrid Natural Polymer Composite Prepared with Banana Stem, Pineapple Leaf, and S-Glass

Advances in Materials Science and Engineering, 2021
There is more demand for natural fiber-reinforced composites in the energy sector, and their impact on the environment is almost zero. Natural fiber has plenty of advantages, such as easy recycling and degrading property, low density, and low price ...

Flexure with damage [PDF]

Geophysical Journal International, 2006
SUMMARY Ductile behaviour in rocks is often associated with plasticity due to dislocation motion or diffusion under high pressures and temperatures. However, ductile behaviour can also occur in brittle materials. An example would be cataclastic flow associated with folding at shallow crustal levels.

Flexure of cranial sutures [PDF]

Journal of Biomechanics, 1971
Beam samples containing cranial sutures were prepared from embalmed and unem- balmed cranial bone and were tested to determine their flexural stiffness and strength. With the aid of layered beam theory, the flexural stiffnesses of beams containing cranial sutures were compared to hypothetical layered cranial bone beams which did not contain sutures ...

An Estimation of Dynamic Modulus of Elasticity in Cantilever Flexural Timber Beams

Drvna Industrija, 2014
Due to considerable influence of shear deflection and rotary motion, the modulus of elasticity is hardly obtainable in fixed-free flexurally-excited (cantilever) beams. For isotropic materials, Timoshenko has proposed a set of curves to correct the fixed-
