RESUMO:

This work presents a study considering the thermal effects in the dynamic behaviour of nonlinear 2D-frame structures (physical and geometric), in which the effects of bending and shear are predominant. A formulation substantiated on the first and second laws of thermodynamic and the Helmholtz free-energy is presented in this work to consider the thermic effects on this type of structure. The Finite Element Method based on nodal positions, rather than nodal displacements, is used as structural analysis tool. The solution of the nonlinear dynamic problem is given through the combination of Newton-Raphson iterative process with several explicit and implicit time integration methods, wherein the numeric results are compared with the ones found on specialized literature. As well, it is presented a description of one technique to solution of impact problems.
