“…The E was computed in these four different values of L / h for the wood beams, the hollow section rectangular steel tube beams, and the wood-filled steel tube beams. Danawade et al 30 found that the value of the E was high when the L / h values were 27.95 and 13.98 for all the three tested beams. Danawade et al 30 findings agreed with the recommended L / h by ASTM.…”

“…Garoushi et al 29 conducted three-point bending tests on short fiber-reinforced composite resin specimens at six different span lengths: 20, 15, 10, 7, 6, and 5 mm. Danawade et al 30 conducted a study to investigate the effect of span-to-depth ratio on the obtained value of E of wood-filled steel tubes. Four different values of L / h were investigated: 7.09, 14.17, 13.98, and 27.95.…”

“…16). 30,33 Equation (1) can be used to compute the apparent E when the shear deformation is ignored and can be used for specimens with L/h greater than or equal to 16. Nevertheless, equation 1does not consider the shear deformation in the computation of the E. To include the shear deformation (D s ) and the flexural deformation (D f ) in the computation of the E, equation 234-36 can be used, but the values of (E/G) are difficult to obtain.…”

The hygrothermal effect on the short-term creep behavior of extruded thermally modified wood fiber–high-strength styrenic copolymer plastic composites (wood–plastic composites (WPCs)) was investigated on specimens preconditioned for 1 month under water immersion (distilled water (DW) and saltwater (SW)). These specimens were then tested in the same conditions for short-term creep and creep-recovery response using a submersible clamp. The short-term creep tests of WPC specimens (that are immersed in water as a function of different temperatures) have not yet been reported in previous studies. The objective of this study was to determine whether the hygrothermal creep response of WPC material evaluated through water immersion differs from the creep response published in the literature for other environmental exposure conditions. The experiments included measuring 30 min of creep and 30 min of creep recovery on the specimens immersed in SW and DW at two different levels of flexural stresses (9% and 14% of the flexural strength) and three temperature values (25, 35, and 45°C). The average creep strain recovery (%) of the specimens was higher for the specimens immersed in SW during testing than the control specimens. The WPC material is considered to have a potential use in structural applications in environments where the temperature is below 45°C because of the following factors: the low deformation under the short-term sustained loading, the decrease in the deformation rate with respect to the increase in load duration, maintaining the modulus of elasticity over a range of temperatures from 25°C to 45°C under sustained load, and the ability to recover more than 69% of the average creep strain under water immersion when the loading source is removed. The creep strain fractional increment (CSFI) of the WPC in this study under all conditions was 13% which is 86% lower than the CSFI of the WPCs reported in previous studies.

“…Their study however was limited to sandwich beams with a particular shear span resulting to beams with different shear-span ratios making the direct comparison of their behavior inadequate. Many researchers [15][16][17] indicated that shear span-to-depth ratio has a strong influence on the failure behaviour and structural performance of the sandwich beams. Manalo [18] investigated the behaviour of phenolic-core sandwich beams in horizontal orientation with different shear span-to-depth ratios.…”

AbstractThis study thoroughly investigated the flexural behaviour of phenolic cored sandwich beams with glass fibre composite skins in the horizontal and vertical positions. The beams have a shear span-to-depth ratio (a/d) varying between 0.5 and 12, and tested under 4-point static bending. Their failure load are then predicted theoretically. The results showed that changing the beam orientation from horizontal to vertical changes the failure mode from brittle to progressive. The sandwich beam's high bending stiffness can be efficiently utilised by placing them vertically. The a/d ratio played a major role on the load capacity and failure mode. In both orientations, the load capacity decreased with the increased of a/d. The beam failed in shear, a combined shear and bending, and bending for a/d ≤ 2, 2 < a/d < 6, and a/d ≥ 6, respectively. These failure mechanisms can be correlated to the shear-to-bending stress ratio while the failure load can be reasonably predicted using the available theoretical models.The two-way analysis of variance showed that the beam orientation is a more influential parameter than the a/d ratio. From this study, the horizontal beams are preferable for flexural dominated structures while the vertical beams are desirable for shear dominated structures.
