Abstract
Sandwich structures are mainly used due to its low weight and high strength supporting compressive and flexural strengths, also showing excellent thermal insulation characteristics. Nowadays, sandwich beams are requested in many applications like aviation, missiles, boats and civil construction which demands an analytical method to predict its properties. It consists in a core rounded by a lamina or a laminate in both of your sides. Core’s main function is to guarantee a high moment of inertia. The kinematic behavior of sandwich structures has been described based on formulations of laminated plate theories. This paper brings an analytical model for sandwich beams assisted by software, computed through Python algorithms. The software uses a database with properties and other pertinent information that serve as the basis for calculations. The user interface is user-friendly and allows calculations to be done more quickly and improves your experience. The analysis are based on classical laminate theory and Timoshenko plain beams deflection, since it attempts for the transversal shear displacement. As inputs, the program needs to be entered the core and laminate types, provided in its database, dimensions like height, breadth and length. As outputs, user obtains flexural rigidity of sandwich beam, core and face stresses, shear stresses, buckling, deflection, mass and shear strain area for non-homogeneous-isostatic beams.
