Determinação dos esforços em lajes pelo métodos dos elementos de contorno

Through deductions and formulations of the equations governing the behavior of plates elastic and thin based Kirchhoff theory, it is evident that it is justifiable to the complication of the numerical methods considering the complexity of the equations that describe the physical behavior of these elements and obtaining analytical solutions for specific situations. This study is directed to the application of the numerical method which is based on discretizations to the simplest elements which results in the reduction of data to be processed from. The numerical method in question is the Boundary Element Methods (BEM), as the name suggests, the discretizations are only the edges of the elements. The BEM converts the complex integral equations, in sums of functions that reduce the unknowns at the nodes that define the ends of discrete elements, obtaining internal values to elements using interpolation functions. Confirming the need and usefulness of the BEM, apply, then the foundations necessary to the specific cases of Civil Engineering where traditional methods do not provide the desired support, leaving in question the security situations and economics of the projects

Fins are a way to improve heat exchange, they increase the surface area in contact with the fluid medium. Besides widely used in industries, such extended surfaces appear in various formats and can be compared for their efficiencies in order to select the most profitable. This work proposes a new profile of fin so as to increase the perimeter of the base. The raised profile cross sectional area is constant and is also compared to other types. Here are shown the deductions of equations for this new element, and through the perimeter and graphs calculated results are compared
