LESM is a free software for static linear-elastic analysis of two-dimensional and three-dimensional linear elements structure models.
The program handles five different types of analysis models of reticulated structures: 2D (plane) Truss, 2D (plane) Frame, Grillage, 3D (spatial) Truss, and 3D (spatial) Frame.
In addition, two types of flexural behavior for linear elements are considered: Euler-Bernoulli (Navier theory) elements and Timoshenko elements.
The program has a graphical user interface of simple usage that supports mouse interaction for modeling and analyzing results.
The Object-Oriented Programming (OOP) paradigm is adopted in the implementation of the analysis process. The use of OOP is justified by the clarity, organization and generality that this programming paradigm provides to the code.
