| Resumo: | This paper aims to study the thermomechanical behavior in bidimensional solids,
taking into account the physical and geometric nonlinear effects. To consider the
thermal effects, a formulation based on the first and second laws of thermodynamic
and the Helmholtz free-energy is presented here. It is essential to analyze the
thermoelastic and thermoplastic behavior in dynamic structural response. The Finite
Element Method based on nodal positions, instead nodal displacements, is employed
as geometric nonlinear formulation. For dynamic problems, a temporal discretization
by several temporal integration algorithms conduces to the equation of motion solution.
In addition, this formulation can be extended to impact problems. Therefore, the
development of computational routines for the proposed formulation induces numerical
results are compared with examples from the specialized literature. |
