Estudo do fenômeno de flambagem elástica em barras prismáticas utilizando visualização gráfica

Abstract

Due to the current technological availability, a very relevant resource for the study of physical phenomena, especially those that are not easily accessible to experimentation, because the difficulty of visualizing or executing the experiments, is the use of graphics visualizations. This type of computational application allows modeling the problem and manipulating the variables to obtain in real time a response of the behavior of the phenomenon. One of the phenomena studied in structural engineering is the loss of stability due to buckling, which depends on several parameters, such as longitudinal elastic modulus and geometric characteristics of the section and the member, making this effect essential to the study of structures, especially in the presence of slender parts. However, it is not always easy to determine, at a glance, how different models behave. Thus, combining the resources computational data to a mathematical model of the phenomenon, the objective of this work is to make a study through the development of a computational simulation program based on visualization the phenomenon and analyzing cases its help, having a more complete understanding of the phenomenon and its behavior into the various variables that influences it.
