| description | The objective of the project is to investigate the relationship between the
stress-strain characteristics of oil palm trunk vascular bundles and its moisture
content. Based on the stress-strain graphs, the mechanical characteristics are
then related to the microstructure of the vascular bundles. The results show
that for all samples tested, 3 zones of deformation are found i.e an initial zone
that is slightly curving, a plateau zone and finally a linear zone. The existence
of the plateau zone is then explained in terms of the vascular bundle
microstructure. AJ; a result of the presence of the plateau zone, the stress-strain
curve is then described by 2 modulus of elasticity i.e the initial modulus and
final modulus. The final modulus was found to be higher than the initial
modulus thus indicating that the vascular bundles become stiffer after
encountering the plateau zone. The maximum stress and final modulus of the
vascular bundles were found to increase when the moisture content of the
vascular bundles decreased. |
