Comparative Finite Element Analysis of Jaipur Foot and Polyurethane Foot
FEA is amongst best methods that help users to solve complex problems. There are fixed number of nodes in each element of the model that define the element boundaries to which boundary condition and loads can be applied. The geometry of the structure, the load applications, stress and displacement gradients can be approximated in a accurate manner, if the mesh is finer. The problem with the foo...
متن کاملThe Jaipur foot.
The Jaipur foot was developed for barefoot amputees by Professor P. K. Sethi. He used local artisans and readily available materials. The prosthesis was cheap and could be made in one hour. It enabled amputees to work in rural conditions, muddy and wet fields and to climb trees. It has been widely used in India, South East Asia and Africa, where local variations to the design have now been made.
متن کاملFinite Element Modeling of the Human Foot and Footwear
A finite element (FE) model of the human foot and ankle was developed from 3D reconstruction of 2 mm coronal MR images from the right foot of a normal male subject using the segmentation software, Mimics. Solid models of 28 foot bones and encapsulated soft tissue structures models established in Solidworks software were imported into ABAQUS for creating the tetrahedral FE meshes. The plantar fa...
متن کاملEquipment and methods for laboratory testing of ankle-foot prostheses as exemplified by the Jaipur foot.
A load deflection and a cyclic loading apparatus capable of measuring dorsiflexion/plantarflexion, pronation/supination, internal/external rotation, and cyclic dorsiflexion (60 cycles per minute) of ankle-foot prostheses are described. A test protocol was developed to assess the functional parameters of the Jaipur ankle-foot prosthesis before and after prolonged cyclic loading, with the simulta...
متن کاملMuscle-driven finite element simulation of human foot movements.
This paper describes a finite element scheme for realistic muscle-driven simulation of human foot movements. The scheme is used to simulate human ankle plantar flexion. A three-dimensional anatomically detailed finite element model of human foot and lower leg is developed and the idea of generating natural foot movement based entirely on the contraction of the plantar flexor muscles is used. Th...
