In this paper, values for flexural
and torsional stiffness, as well as the twist-to-bend ratio, are reported for crinoid arms (Echinodermata, Comatulida) and crustacean antennae (Arthropoda, Decapoda).
The result of flexural
test is shown in Table 2 and in figure 4.
Thereafter, the optimization algorithm is entrusted with the indubitable task of predicting various parameters such as optimal compressive strength (Mpa), split tensile strength (Mpa), flexural
strength (Mpa), and deflection (in mm).
Afterward, five (5) samples of both plaster A and plaster B are prepared according to water /plaster ratio of 50%, 60%, and 70% before subjected to the flexural
testing which was done according to ASTM C293-08 .
It was concluded that composition of dental composite materials significantly affects their flexural
Specimens were tested for flexural
resistance on the Hounsfield tensometer (Tensometer Ltd, England).
Replacement of 10% of fly ash by OPC in GPC mix resulted in an enhanced compressive strength, split tensile strength and flexural
strength by 73%, 128% and 17%respectively with reference to GPC mix.
Current design code ACI318  suggests that flexural
strength of reinforced concrete section can be calculated by
The effect of NaOH concentration on the flexural
properties of kenaf fiber, PALF and mengkuang fiber will be addressed in the next sub-sections.
2 it can be seen that chemically pretreated wood flour gives better coupling with the polymer matrix and thereby better flexural
strength values than composites with untreated wood flour.

properties were determined according to ASTM D790 and performed on a MTS QTest/25.
