| Summary: | One of the objectives of this paper is the development of a computational code based on the positional finite element method, which uses any hyperelastic constitutive models to simulate the flat behavior when subjected to large displacements and large deformations. It is also an integral part of the objectives of this paper to develop a formulation based on the positional finite ele-ment method and an innovative strategy of immersion of finite elements of the simple bar type into elements of the plate type. This formulation should be able to include both viscoelastic and active behavior, as well as to allow the consideration of nonlinear relations between stresses and deformations. It is common to adopt hyperelastic constitutive laws. Few are the works that use the strategy of approaching the problem such as fibers immersed in a matrix. The immersion of fibers in the matrix makes it possible to include both a viscoelastic behavior in a simple and direct way. The examples are simple cases, some of them even with analyt-ical solutions, mainly for validation purposes of the presented formulations. By modeling a structure, the examples show the po-tentialities of the concepts and proposed formulations. |
