About the thesis<\/h3>\n

This PhD Thesis aims to contribute to the development of finite element methods for the analysis of stamping processes<\/strong>, a problem area with a clear industrial application.<\/p>\n

To achieve the proposed objectives,the first part of this thesis covers the elements of solid-sheet<\/strong>. This type of element is attractive for the simulation of forming processes, since any type of three-dimensional constitutive law can be formulated without the need to consider any additional conjecture. Additionally the contact of both faces can be easily treated. This work first presents the development of a triangular prismatic solid-sheet element<\/strong> for the analysis of thick and thin sheets with the capacity for large deformations. This element is in total Lagrangian formulation<\/strong>, and uses neighboring elements to be able to compute a field of quadratic displacements. In the original formulation, a modified right Cauchy tensor was obtained; however, in this work, the formulation is extended obtaining a modified deformation gradient<\/strong>, which allows the use of push-forward and pull-back concepts. These concepts provide a mathematically consistent method for the definition of temporary derivatives of tensors and, therefore, can be used, for example, to work with elasto-plasticity. This work continues with the development of the contact formulation used, a methodology found in the literature on computational contact mechanics for implicit simulations.<\/p>\n","protected":false},"excerpt":{"rendered":"
