A finite element models to (FEM)
of the human foot, especially the experience of foot
deformities such as pronation, Metatarsalgia, Flat
Feet, Neuroma, Plantar Fasciitis, Arch Pain, and
diabetes can be quickly developed and dealt into
3D solid .STL file using foot scan IQube 550. Solid
abnormal human foot model consists of plantar
facia and encapsulated soft tissue (indenter feet)
with EVA rubber insole will be built into a 3D
solid orthotic shoe insole in PowerSHAPE CAD
2015 then imported into the software ABAQUS
6:13 into 3D meshes FE analysis. Contact
interactions that occur and be studied is between
the indenter foot with shoe orthotic insole designed
in various sizes. Abnormal foot contour obtained
by the scanning process. Strategy curve-based
surface modelling (CBS-modelling) was applied in
this paper to obtain surface and solid models of
shoe orthotic insole. 3D will be made some orthotic
shoe insole to provide the size of the gap between
the soles of the feet to the width of the insole
designed. EVA rubber is used as an insole material.
FEM analysis is used to obtain von misses stress
from loading that varies on each insole with a
predetermined gap width. The prediction results
with FEM Abaqus 6:13. The result of the 3D solid
with optimal insole shoe orthotic peak of 1,190x10
3
MPa von misses stress on the heel bone to the gap
width of 1.75 mm
