    abstract = {This research concerns developing a composite
material which can be used in manufacturing prosthetic
feet with a reasonable cost and satisfying mechanical
properties. The characteristics were investigated by
mechanical tests of tensile properties and Charpy impact
strength. The study of date palm wood and its effects on
the mechanical properties of polyethylene have received
little attention. It was found that Young’s modulus of 40%
High Density Polyethylene (HDPE) filled with sixty
percent of Date Palm Wood (DPW), significantly
increased to 80% compared with pure HDPE. Moreover,
the yield and ultimate stresses were improved which was
approximately two times higher than that observed for
pure HDPE; the elongation at break and impact energy
were decreased significantly. The characteristics exhibited
by prosthetics compared to those of a human foot were
investigated further. The analytical section presents the
results of the static analysis by numerical methods (Finite
Element Method FEM), ANSYS Workbench 14 and
experimental methods. Thus, the new foot was
designed and the dorsiflexion was measured. Overall, the
non-articulation of this type of foot is compared against
the SACH foot by cost and weight, so that, the cost of the
non-articulated foot is lower than that of the other by
about 60%. We also found the new weight is lighter than
that of by about two percent. The new model of prosthetic
foot has better characteristics which includes foot life
cycle (7.5° and 1,049, 135), respectively when compared
with the other (6.4 and 896213), respectively.}
