Effect of the Number of CFRP Prepregs and Roughness at the Bonding Area on the Spring-Back and Flexural Strength of Hybrid Composites of CFRP Combined with CR980

Metals, 2019
Hybrid composites in which a CR980 metal plate was bonded on carbon-fiber-reinforced plastic (CFRP) were prepared. Hybrid composites were two types of CFRP/CR980 hybrid composites and CR980/CFRP hybrid composites.

Finite element model of bamboo culm (Phyllostachys sp.) and its comparison to two experimental tests

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
The main goal of the work was to build up a general parametric finite-element model of a bamboo culm in ANSYS computational system. Subsequently the model was compared to a experimental measurements of chosen mechanical properties – three point bending ...

Acoustic Emission Characteristics and Damage Evolution Analysis of Sandstone under Three-Point Bending Test

Advances in Materials Science and Engineering, 2023
In order to study the prevention of roadway roof bending, sinking, and breaking and the prevention of dynamic disasters such as the appearance of rock bursts, three-point bending experiments of sandstone under different spans were carried out.

Comparison of behaviour of burnt beams models with effective and actual residual cross-sections in three point bending test

Acta Polytechnica CTU Proceedings, 2023
Glued laminated timber beams exposed to fire of a variable duration were tested in three point bending. Three types of model geometries taking into account the effect of burning were created. Each model was examined for five material data sets.
