Abstract

The growing evolution in Solid Mechanics makes possible very important improvements of world biomechanical applications. These applications are important to the improvements of health conditions of human beings. Some application as angioplasties, artificial hearts, orthopedic prosthesis, among others, can be mentioned. The better knowledge of muscular behavior allows the design of less invasive devices.The objective is the development of a 2D FEM formulation to learn the muscular behavior using an alternative heterogeneous constitutive model looking forward to 3D applications. Beyond the material objective, the development of a student of mechatronic engineering in the field of biomechanics is a very desirable achievement.The material objective can be summarized in: To study the one-dimensional model of Hill for biomechanical material in order to implement immerse fibers in continuous media. To adapt the existent tool for the 2D geometrical non-linear analysis of solids with passive fibers to comprises active fibers. To adjust the existent sinuous fiber generator in order to reproduce the fasciles geometry. To make initial tests in static examples in muscular structures using the Saint-Venant-Kirchhoff model for the soft (passive) tissues. To develop simple biomechanical tests (2D) for active forces in articulate structures (arm) using a basic anatomy and a illustrative two-dimensional discretization.
