2. List of finite element software packages - Wikipedia

   en.wikipedia.org/wiki/List_of_finite_element...

   GOMA is an open-source, parallel, and scalable multiphysics software package for modeling and simulation of real-life physical processes, with a basis in computational fluid dynamics for problems with evolving geometry. A generic finite element library written in C++ with interfaces for Python, Matlab and Scilab.

3. Dia (software) - Wikipedia

   Windows, OS X, Linux, Unix. Type. Diagramming software. License. GPL-2.0-or-later. Website. GNOME Apps. Dia (/ ˈdiːə /) [3] is free and open source general-purpose diagramming software, developed originally by Alexander Larsson. [1] It uses a controlled single document interface (SDI) similar to GIMP and Inkscape.

4. Shear and moment diagram - Wikipedia

   en.wikipedia.org/wiki/Shear_and_moment_diagram

   Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.

5. Finite element method in structural mechanics - Wikipedia

   en.wikipedia.org/wiki/Finite_element_method_in...

   The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at discrete points called nodes.

6. Free body diagram - Wikipedia

   en.wikipedia.org/wiki/Free_body_diagram

   In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).

7. Direct stiffness method - Wikipedia

   en.wikipedia.org/wiki/Direct_stiffness_method

   In structural engineering, the direct stiffness method, also known as the matrix stiffness method, is a structural analysis technique particularly suited for computer-automated analysis of complex structures including the statically indeterminate type. It is a matrix method that makes use of the members' stiffness relations for computing member ...
